Every guide on this topic has a list, and most of the lists are the same fifteen items in a different order. Some of those items come from Valve. Most come from other guides. Since the score is hidden and the formula is hidden, nobody outside Valve can test which items work, so the honest version of this article has three parts: what Valve has confirmed in writing, what the community added without a source, and what we have measured ourselves on millions of profiles, which is about bans rather than Trust Factor and will be labelled that way every time.
What Valve Actually Confirms
The official FAQ has a question called “What can I do to improve my Trust Factor?” and the answer is short: “The only way to improve your Trust Factor is to be a positive member of the Counter-Strike 2 and Steam community.” It continues: “all players have to do to improve their matchmaking experience is continue playing Counter-Strike 2 and other Steam games legitimately. The more a user plays, the more information the system has and the easier it will be for the system to determine who they should be matched with.”
That is one confirmed lever: play, cleanly, over time. The second is one paragraph down, under “Does Prime status improve my Trust Factor?”: “Yes. Phone numbers and Counter-Strike 2 Rank are among the factors used in the new Trust Factor matchmaking system.” Valve goes on to encourage linking a phone number, “doing so will improve your matchmaking experience.” So a phone number on the account and a CS2 rank are named inputs, in Valve's words, which is rarer than it sounds.
The third confirmed idea is the oldest. The 2017 announcement described the system as “matching players using observed behaviors and attributes of their Steam account, including the overall amount of time they had spent playing CS:GO, how frequently they were reported for cheating, time spent playing other games on their Steam account”. Time in CS2, reports, and time in other games. Trust Factor was Steam-wide from day one.
What the Guides Add, and Where It Comes From
Now the rest of the usual list: make the profile public, raise your Steam level, buy games, write reviews, post screenshots, add friends, avoid leaving matches, stay off the mic when tilted. Some of these are probably right. Not one of them appears in anything Valve published. They are inferences from the phrase “positive member of the Steam community”, repeated until they read like facts.
We are not going to tell you they are wrong. We are going to sort them. Behaviour items, finishing matches, not griefing, not getting reported, line up with the one input Valve named in 2017, reports. Account items, phone number and rank, are named in the FAQ. Everything else, level, reviews, screenshots, badges, is a guess about what “positive member” means to a system nobody can see. Treat those as hygiene, not as levers with a known weight.
What Banned Accounts Have in Common in 19.9 Million Profiles
This is the part we can measure, with one big label on it: we measure bans, not Trust Factor. A VAC or game ban is public and permanent, so we can collect millions of profiles and ask which public signals banned accounts share. That does not tell us the matchmaker's weights. It does tell us which public traits travel with the accounts Valve eventually removes, and those are the traits worth not sharing.
Show the numbers
| Accounts sharing the image | Accounts | With a ban |
|---|---|---|
| 1 (unique image) | 1,806,159 | 14.71% |
| Exactly 2 | 62,468 | 19.12% |
| 3 to 5 | 75,153 | 14.64% |
| 6 to 10 | 50,110 | 14.16% |
| 11 to 100 | 191,155 | 10.46% |
| 101 to 1,000 | 261,946 | 8.77% |
| 1,001 or more | 187,247 | 8.68% |
| Default Steam avatar | 199,591 | 4.09% |
Our first pass at this got the sign wrong. Lumped together, “shared avatar” looked safer than a unique one, 9.48% against 14.71%, because the default avatar with its 199,591 accounts dragged the average down. Only splitting by group size showed the real shape. We mention this because the popular guides never show their working, and a signal like this one flips depending on how you cut it.
The second measurement is about company. We pulled the friend lists of banned accounts and the friend lists of clean accounts from the same Steam group, and checked how many of each carried a ban: 18.94% against 9.02%, with random SteamIDs at 9.64%. The control group is what makes the number mean something, because it rules out “CS2 players just know CS2 players”. We wrote that one up in the post about queuing with low-trust friends. The third is smaller but clean: profiles with a real name filled in showed a ban 11.56% of the time against 14.03% without one, across 2.83 million accounts.
None of this is a formula. It is a list of public traits that banned accounts share more often than clean ones, measured after the fact. If you control a trait on that list, the avatar you use, the accounts you keep on your friend list, the fields you fill in, you can decide what your profile looks like to anyone reading it. Whether Valve reads it the same way is the one thing we cannot check.
A 15-Day Plan You Can Verify Field by Field
Here is the practical version. Run your profile through our Steam Profile Checker. It reads 74 public fields, tells you which ones are dragging the reading down, and which are holding it up. Then start the 15-day program. It gives you a list of changes, ranked by how much each one moves the reading. You make a change, mark the card done, and we re-read that exact field on your profile and confirm it. Not the score, the field: “reviews read 0, now reads 3”. We check again by ourselves 48 hours later and at day 15, and you keep the before-and-after for 30 days.
The program verifies fields because fields are the only thing anyone can verify. A guide that promises “green in two weeks” is promising to read a number Valve hides. We would rather show you a public field changing, with a timestamp, and let Valve's system do whatever it does with a profile that now looks less like the ones it bans.
Where Commendations Fit
Commendations are one of the few positive signals you can add rather than wait for, and they are the reason this blog exists. The honest version of that sentence has two halves. Valve has never named commends as a Trust Factor input, so we do not claim they are one. And where they come from matters more than how many arrive: commends from aged, clean accounts with history are a different object from a burst off a free bot, which ties your profile to exactly the accounts on the wrong side of the chart above. We covered whether Trust Factor goes up with commends and why free commends backfire separately, with the same caveats.
What We Won't Promise
We will not promise a colour, a number, or a date. Valve does not show the score to anyone, including us, and the FAQ says “Trust Factor matchmaking will continue to be adjusted”, so any claim about the formula has a shelf life measured in patches. What we promise is narrower: a list of public signals ranked by evidence from our own data, a way to change the ones you control, and proof on your profile that the change landed. Play cleanly on top of that, the one thing Valve actually asks for, and you have done everything a player can do.
