measure against cheating

Hi,

On FICS:
There is a player, Opinel, who was often accused of cheating, because of very high rating(and chess performance also) and also probably because of his (silly in my view) notes.
Recently, when they planning to ban him, Opinel contacted the site admins and submitted his GM certificate, so it seems the accusations were not correct.(ok, a GM can still use a computer and cheat, but the probability is very low).
Maybe this should be a good idea to use on this site: when a player rating gets too high, ask them to prove somehow that they are titled players or something, to prove in a way their real life chess.
What do you think ?

I think its a good idea.
I think it can be used in conjunction with other techniques.

What do you think ?

GM OTB or Correspondence? I ask because many associations DON'T check for chess engine use, or even care.

Also, what is their win percentage? If they are GM but lose 5 or 6 percent of the time but NEVER lose on a chess site chances are they are using something to their advantage.

Also also, no human thinks like a computer. Regardless if they are GM, there is no way they should be evaluating millions of positions and constantly matching an engine.

Anyone can cheat. No change required.

P-

Wasn't there once someone who checked suspect players' games to see what percentage of their moves were exactly what an engine would do? Or am I thinking of another site?
