Impersonating an SR or Partner Admin or Partner MM Those will receive an insta-ban on sight, where the following is observed: Nickname matches enough, for instance if someone impersonates "Mattie!", it will also count if the scammer's name is "[SR-A] Mattie! - Selling Burning TC" Avatar matches. If avatar doesn't match, and the nickname is "generic", e.g.: "Mattie" (notice no exclamation mark), we need proof of abuse of reputation of someone else. Notice that we don't require proof of abuse of reputation in those cases. Impersonating another user or pointing to someone else's reputation thread. Claiming to be an "alt" of a reputable user or pointing a to their reputation or profile, is mark-able. Almost invariably these users try to get the other trader to trade items first to them in a real world money trade with steam or game items. Variations also exist where another account previously added the victim, never said any, and when the "buyer" of items asks to trade items for some kind of "inspection" or "check" to a close friend, they will try to impersonate the victim to the "friend" in order to try that the friend trades to them instead of to the victim. There must be an intent to abuse someone else's reputation to gain advantage in the trade. This can be in many forms: Full nickname, Avatar, profile texts, formatting of stuff, steam badges, etc. Pointing to said account, saying they are an alt of it. Pointing to said account's reputation thread(s), saying its theirs. Impersonating the victim to a friend of the victim to get items traded to them instead of back to the victim. Or even impersonating the friend of the victim. Note: As I'm writing this off the bat, I probably forgot some exclusion/inclusion cases, and some cleanup might be needed for clarification etc.
