Maybe, but you may be underestimating how much damage a few dedicated
players can do. This one player accounted for about 8% of the games
against CrazyStone since November, and because he lost so many games
against solid bots, he affects the rank even more than a regular player.

I think waiting months for old games to expire when you make an
improvement is not so good. If I was running bots on KGS I'd have 7
rotating accounts, and only play an account for a month so that it
wouldn't get heavy.

It's a lot easier than you think, and I've reported a few people where
something is clearly being abused, whether it is sandbagging or cheating
to get a higher rank.

Zen19d is already winning 64% out of 59 games that are even and 56% out
of 27 against higher rank since November:

I would be very surprised if it isn't 6d in 2012.
