As a DM I once took a person aside and had a hygiene discussion with them. I had had complaints from the other players and really had no choice. I don't tell people they aren't allowed to stink but I did, that time, have to tell someone they were not allowed to stink to the point that it would drive other players away from the gaming table. If this happened at a convention where the others players had the additional clout of having paid for their right to play in a reasonable environment, I feel I would also, as DM, have no real choice but to take someone aside as necessary, the same as I would with a player displaying any other type of disruptive behavior. It took for a few months and then that particular group split up. I have no idea if that one player continued to wash regularly.
