At present to create a forum account takes circa 30 seconds, Olga has said that they shall ask for email account confirmations, I find creating such a web email account to be a pain in the butt and it takes significantly longer than 30 seconds.
At least we're moving in the right direction, I don't know if possible but rather than just IP tracking, cookie tracking also. I know the mods are on the ball as far as more than one user at the same IP address, so users change IP address, if they also need to delete cookies, aswell as changing IP, then this makes it more of a pain in the butt each time they want to play silly buggers.
And ..... perhaps as soon as an offender slips up, is exposed by IP or cookie tracking, then the mods cancel one or more of that person's member accounts.
as some of you know running a forum is a lot of work. you get spammed every single day with advertisement. there is also those who fight and bicker ( not all bad for a forum) the fighting and bickering is like a daytime soap or Jerry Springer show. it keeps people coming back to see what the fighting is about. for those who do act like children with nothing more to do than try to get attention, they help keep a forum active and that is the key to getting more users and keep people coming back.
