If you look through the code for eacxh page you'll find this
The site isn't blacklisted, doesn't have malware, iframes, or redirects (just scanned it). It WAS suspended just days ago, when I looked...so maybe they cleaned it up, and Google reviewed it and confirmed it was good to go?
I mean, it will take a day or two for some ISP's to pick it up.
As far as the script goes...it's in the software footer (not the additional site footer), so if you go into the board's main index template (or a separate footer template that is called through the main index...can't remember how vBulletin has it set up), you should be able to just remove it. I really don't see a reason why it's there. Maybe an ad was placed in the footer a LONG time ago, and it wasn't completely removed when it expired? Sounds like their icon (whoever it is) was added a while back, maybe for doing something with the site's banner, and eventually, their site became inactive and was hit with malware...which would result in the blacklist, and the warning on here (and anyone else who had the icon). Of course, that's all speculation, because I haven't been here long enough to know...but that seems likely.
If you guys need any additional help, just let me know. I know it would be tough to trust someone, but I've been coding and running message boards since 2005, and I don't care about being paid for anything, either...it would be a simple fix. Just seems like a small nuisance for a board that has 12 million or more posts, not really worth losing members over (if they decide to panic, no real reason to...but you can't blame them).
