risko_ has is not playing in any of my games, but he's just shown up in the chat of two of them with factually incorrect accusations against MikeZoo.
He says Mike missed "many" turns in a particular game, in order to avoid turning in cards. I chacekd the log of that game. Mike did miss one turn (not many) and plausibly (but not verifiably) claimed it was for other reasons. The possibility of intentional missing came up when risko_ (that's right) missed a turn, Mike got angry (but civil) accusing risko_ of doing it intentionally, risko_ admitted as much and got stupid and defensive.
So risko now, in addition to missing turns, is lying (and I use the word advisedly; I'm sure he knows that many != 1) and spamming.
