Idk an exact number but every time ive gone on in the last couple days it has been flooded with spammers every 10 minutes. It's better than PO but its still annoying. Maybe one message every second with a limit of 1 on the number of links you can post in one message? I do like the fact that you have to register and win a match before you can post, though
And my only other complaint is: please make the user list alphabetical. It makes finding people impossible =[
