Actually, this got resolved, and it turns out that the mtgross guy who signed up after metagross111, you and the 3 others got banned was not metagross111, but an imposter. The first attack was meant as a joke by you all, but the second attack was a deliberate attack by anonymous people (altough me and others have a big idea of who did it). The guy registered multiple accounts including one to impersonate metagross111, but in a sneaky way so we don't notice the multiple accounts, just one. It is clear it is who I think because it seemed planned in function of how we blocked the spam attack on the Omnimaga temporary board and the IRC channel back in February and one of the other 3 spam attacks that occured in the channel afterward. The spammer knew registrations would get disabled and he would get banned, so he registered multiple accounts under different proxies so he could still spam again even after registrations are disabled. I won't tell who it could be, but I am not alone to think it is him and we have some indications that makes it more sure it could be that person, such as IRC logs. Per precautions mesure, I deleted every accounts registered on TIMGUL after February. Some other accounts seemed suspicious so I didn't took any chance.
If, however, by the time registrations are disabled, I notice more spam on TIMGUL from suspicious accounts I never saw before or anything implying that the disabled registrations was bypassed, then it will mean we are getting hacked and I will be forced to take both Omnimaga and TIMGUL down until SMF releases SMF 2.0 Final or a 1.19 patch. Hacking/cracking is less likely to be the case, though. On top of that there are daily backups for Omnimaga being done and the entire hosting space content was backed up last night. This is not to mention that if the hacked did one thing wrong and accidentally revealed himself then he could get into serious trouble.
