I actually did a little sleuthing and provided them with information that appeared to lead back to a particular spammer (all those "watch such and such sports event live online" posts). I don't know if they ever followed up with this individual or not or did their own research.
Making the signup process require a working non-free email account might help, but I'm sure there would be pushback.
Isn't there some kind of spam filter on these forums? can't you block registration by domain or something?
