In the form of Aaron clearing it all out manually.
The sad part is that this crap is posted by actual people, not robots. They manually type in the CAPTCHA (I can see this in the logs).
The easiest solution would be to turn on admin approval for new accounts but this would mean several times a day I'd need to check for any pending registrations. Not a realistic scenario.
There are several anti-spam Snitz mods that at least make it only a few clicks to delete. I guess I'd just need to implement them. Snitz is very old at this point and development has ceased. Thing is that there aren't very many forums which run under ASP and even fewer that import from Snitz. vBulletin does however that requires PHP, which in itself is a steaming pile of security holes.
I was looking at a method of forum for the website my work is working with me to put up. The problem is finding a cheap one that will work great for years to come, with minor maintenance from myself and my boss. This has proved tricky.
If you don't have the time to do it right, when will you have the time to do it over?
That's actually one of the reasons I picked Snitz. It is free and runs under ASP. But that was way back around 2001 or so, and I think around 2008 was the last update. It's also made more difficult because I don't run the baseline Snitz code but instead I've modified it. For example, to support file attachments. There aren't too many forums that import Snitz stuff and even moving it from Access (yes, the DB is in Access) to MySQL has proved difficult (though I have succeeded with a test DB).
vBulliten is about the only one I'd consider these days but it comes at a cost of both buying it and having to run PHP. It really also wants to be running on Apache.
There are some free forums out there but most are truly awful like Discourse. Discourse doesn't even know how to scroll.
