great guide, let me add to it
rearmed also track your payment processor, ie, bought prio with the same cc name/details as a previously banned acc, i suspect these are the "2:30" bans, as theyre generally always "cheater alt" bans, also can confirm i know 1 such person who was refunded the same time they received their "alt" ban
staff, even the non CT staff use steam apis, to check accounts, so if you're buying an "aged" account, don't edit them, nothing screams bought more than an account not being used for a year+ then suddenly having profile name/region/everything edited on the same day it started playing on rearmed. put your id in steamid.co.uk for an example of acc history
also if you're excpecting the pc check, great video:
