Well, that's just another element of strategy. The more powerful players need to be defeated. If you're that much stronger, you have to deal with it by outplaying your weaker opponents. Also, ganging up (and being ganged up on) is what makes Four Player Chess so special. Being able to see ratings adds the strategy of whom you should attack. That's not a bad thing.

I suggest that all players be anonymous during the game. That way collusion is impossible

@lazarus_low thats a very good point actually, there seems to quick be situations of ganging up on someone. Especially with checks
I do think this is a very good idea and would eliminate much unfortunates presently going on, and then after the totals appear from the finished outcome then we see who played, won, etc.
