He wasn't cheating at the time but I do believe he does cheat because he also mentioned to the other person the key is not to use it every match, so I think what he does is he only uses it on every 5th match he plays, something like that.
What would be the point of that though? xD
I really don't get it, some of these guys are decent players...yet they still somehow need to cheat? Boggles my mind.
