Ok it's not what I was looking for.
I'll give you some names off the top of my head that do or may deal in porn besides CWS.
adult-links
about
:blank (a real pain to remove)
websearch
surfsidekick
exactadvertising/exactsearch
xxxtoolbar
browseraccelerator (I had to reinstall IE to get rid of that one! it kept coming back)
ezula
searchscout
ILookup
virtual bouncer
easy search - easysearch
safesearch
elitebar
ISTbar
p2p networking
purityscan (not sure if it still exists?)
sidefind
sidesearch
sidebar
tagasaurus
There are a ton of others and many I'm not aware of. Maybe Kellie can add to this list for porn. Since I don't test for this (yet!) I don't know which ones would actually show porn sites and which ones definitely wouldn't.
That should keep you busy for a while anyway.
