Is there a list of words which can get your site 'blacklisted'?

The other day I noticed I had good SERPs for one of my sites for kids on AOL search. About a week later, I used AOL's main website for a search, and it appeared nowhere. I thought I'd been blacklisted. I clicked on the link to remove the adult filter, and my site reappeared on page one of the SERPs.

This is a mystery to me, because the site has no adult content. I haven't the foggiest idea why AOL thinks it's adult. I just found out in Alexa's listing it says: "Adult Content: Yes." More B.S!

Has this happened to anyone else? The site does not have and never had any adult content. I reg'd the domain years ago, and I believe there was no previous registrant or website.

Assuming the AOL and Alexa filters are text-based, they must have a list of words which automatically get your site blacklisted as "adult."

The only word I can think of that is on the site that could be on AOL's list is "sexy" (even though it's not necessarily indicative of adult content). But I checked a two-word phrase including "sexy" and similar sites to mine aren't being filtered.

Any ideas? I'm losing traffic because of a bad AOL filter/algo.

p/g

P.S. It is against my webhost's TOS to publish adult content. It has never received or forwarded a complaint asking for any page or content to be removed.
