My tournaments were specifically ladies only, sooo needless to say the ladies were pissed when the men busted in..
I complained to several poker rooms, to no avail. If someone joins with 4-5 user names, you really can’t do much about it.. unless the poker room is one of the few that does a sign up list, which is just a pain.. or agrees to ban crashers.. shady affiliates… or have some consequence..
I guess what you should be asking is, what are the poker rooms willing to do to put an end to it, especially in the case where the hosting affiliate puts up a portion of the prize pool..
