Nobody is told who liked them
There is no screen that shows you who liked you, and that is a design decision rather than a feature waiting to be unlocked: the information is never sent to your device at all. Identity opens when the interest is mutual, and only then.
You are matched on what you actually play
Your library is part of the signal, and if you connect your game account your hours can come from there instead of being typed in by hand. A shared game with real hours behind it says more than a list of titles anyone can tick.
Reputation follows you here too
The ratings and badges you earn in parties appear on your match profile. Someone deciding whether to like you is not looking at a blank card — they can see that people who played with you would play with you again.
Profiles are reviewed
Introductions and photos go through moderation before they reach other players, and every profile can be reported with a reason. Matching is the part of the app where people share the most about themselves, so it is the part with the tightest checks.
