Poor bastard, the forum has been constantly under attack for at least a month now. Nothing but spammers there: Apache Forum - Apache Discussion Forums, Tips, HowTo's and Resources Can anyone recognize the software used?
If you think I'm trying to state that paid forum software is hackable as well, then no, that was not my intension. I just discovered the site a few months ago when looking for Apache help, and always wondered what software was used.
It's vBulletin, and they've paid to remove the copyright. A good way to tell is by viewing the source of the site, usually the software will have something similar to below (I know vBulletin does): HTML: <meta name="generator" content="vBulletin 3.8.4" />
