Dude, I am sick of this aswell
I have (as you have seen in the Fun Chat E2 I am making.) an E2 script that lets me position a holoEntity on all the players, thus letting me basically manipulate them.
They will regret ever blinding someone in wire. 
cul. what i try to do when finding out who teh blinder is is:
1. kill yourself in console, and this will make the blinder stay in teh position you were alive at
2. you will be able to look around , but as long as you dont click your screen(which will make you respawn)
3. look for any suspicious movement of players. find suspects based on their model they are using in the current game. (eg g man model)
4. if you cant figure out who it is, leave game and re enter with a different name
5.find teh name of teh suspicious players based on their model...
6.teh rest you cant reall know for sure, but use your brain
