alanback: I doubt that Fencer will change any of the actual BKRs. It's probably too complicated a web to unravel and when Fencer eventual gives us a real rating system and recalculates all the BKR histories (lol, are you reading this Filip?! ), having to program in such anomalies would be a real pain in the bum, I expect.
It is a pity that they've affected other's ratings, especially the lower rated players who've been leeched from, but hopefully the fact that they've no longer got any public incentive will mean that they'll stop playing that game in the future. What I'm not sure of is whether Fencer sent them a message or simply implemented the chart ban.
