The UGC Roster Verification tool was commissioned by a fellow friend to solve a very real problem in competitive Team Fortress 2.
This simple tools allows anyone to conveniently verify every individual on the server as long as you have both team's UGC profile URL and the Valve server
Prior to each match, there are uncertainties as to the players whom you play against are really the individuals they claim they are.
The old fashioned way of verifying whether the opposing team's roster is to exhaustively and manually checking each player's name against the team's UGC profile page.
This app saves 90% of your time prior to the match for 100% roster verification accuracy.
(Warning: these statistics may be complete bullshit. But this service really does save people a lot of time.)
