Perhaps someone from the staff should be watching such abuses. Plain multiples arent that bad thing, but if someone uses them to spam boards (sorry Dano) or creating artificial ratings (Joking or someone in chess mentioned earlier), they should be coped with.

As their opponent I would probably resign games with them and add them to my noplay (enemies?) list, perhaps an invisible list would be even better, for such bloody cheaters dont distract me in rating lists :-).

And I am sorry I brought it up so close to Christmas. Merry Christmas to everybody!
