Thread:Project:Support desk/Overwhelmed with spammers

I am one of the admins on this wiki. In the last 2-3 months the spam has greatly increased. From being a few minutes job to removing/blocking to now, over 500-1000 hits a day. I stopped blocking as it doesn't do any good, they just keep coming back in 3fold. I just go and delete and block those that are the nastier, page vandal ones, etc. I am beyond frustruted with this.

Is there a way to shut off creation of new users? any way to do a MASS deletion of current spammers (I would say close to 15K as no way we have that many users that use our wiki site.

I see we have a very old version. I have looked over the upgrade but it is confusing and overwhelming to me, I consider myself a moderate knowledge of computer/internet but this is a bit geek to me.

Here is the wiki page: http://alexbrownracing.com/wiki/index.php/Main_Page

Just really need some assistance with this issue, I have not gotton to new pages yet and I know there is about 300 there, just been trying to clear the mess from the user spammers.

Thank you for any help you can give
