Well, I just signed up for this forum and have been browsing the threads, and I must say that there is a conspicuous level of deleted posts. I *** those are spam messages that are being deleted. If so, then I have to hand it to the moderators/administrators. They're really on the ball.
However, I would suggest modifying your account sign-up process: add a CAPTCHA and other features to foil spammers and keep them from being able to post spam messages in the first place.
From a UX standpoint, getting rid of the "[Deleted by Admins]" would also go a long way to improve the site.
And on a completely unrelated note. I had trouble signing up for a forum account. When I initially used my primary email to sign up, I kept being told by the system that the username was taken (I suspected this was false, since this isn't a very common username). Anyway, after I changed my email address to my work email, the system let me sign up just fine. And this isn't an issue of me having already signed up for an account using the other address either (I searched my inbox and this is definitely the first time I've signed up for a HOWDesign.com accoount).
Anyway, I just wanted to bring that to your attention. And if it helps to troubleshoot, in the past I've encountered registration forms that wouldn't allow me to have a username that's the same as my domain name. But if that was the problem, then your registration system should use a more accurate error message instead of saying the username I selected was taken.
