No, not these forums.
I'm the webmaster for our university's anime convention's website and forums, and our Forums and Guestbook occasionally get some spam. For the Guestbook, it's usually 1 a day, but up to 5 a day (almost always for Viagra), which I have to manually remove in the Guestbook's php code. It's annoying.
For the Forums, we get maybe 1 to 2 a week, but where the Guestbook is just links, these are posts with graphics, oftentimes very graphic porn, which is just unacceptable for our forum of over half being minors and any parents potentially coming to see what we're about.
I check both every day and remove the spam when I can, but we've already had some users mention they'd seen the spam, and that's still too many.
For the forum, it's phpbb, so I'm pretty sure there's code for add-ons like better spam security, but I don't know how to apply it.
Here's a link to the forums so you can better see what you're dealing with (
http://kamicon.forums-free.com/) -- it's hosted by forums-free, so I don't know how to add any code or anything. If someone is willing, I could allow someone I trust (Ame for example, I know she does this stuff) to log into the administrator control to look around.
Here's a link to the guestbook:

All it is is php code, so I don't know if there's really a way to stop spam, unless I could ban specific words from being posted or something.
(The website is built with a for-idiots WYSIWYG program, so I'm well aware that I don't know much code and most things on the site could probably be done better. The only reason I'm the webmaster is because I volunteered and no-one else can/will do it.)
