Hi Zio...just took anther look at your site...and of course, I have a few comments. Wouldn't be me if I didn't have something to say
Entry page...
Didn't notice this previously...your site title might be a bit long for some link lists. Many have a limit of 3-5 words max for title. Also, you'll probably want to put your site title in the title meta.
Your keywords meta is still way over stuffed. Having all those words in there will do no good with search engines and could in fact be considered se spamming. There's really no need to have anything in your keyword meta that doesn't actually show up on the page. Which on that subject, you could certainly add some juicy text to the entry page...perhaps wrapped around a link or 2 to your paysite.
Main page...still looks fine...other than the over stuffed keyword meta and perhaps changing the title tag.
Gallery one...
Pics look fine now...you could wrap some juicy text above/below that top banner ad.
Gallery two...
Same comments as gallery one.
The other issue I see that may put off some reviewers is using 'tgp' in your url. Keep in mind that you're working on free sites which get submitted to link lists. Free sites are completely different from tgp galleries and some reviewers can get a bit cranky if a submitter doesn't seem to realize there's a difference. I'd suggest not using 'tgp' in your free site url's.
No solid advice for you on the blacklist issue. As previously mentioned, I've been seeing more and more domains show up on that list. Also, I can't speak for other reviewers...but for myself, I won't usually link to anything that's blacklisted.
If it's going to be prohibitive to get the domain cleared, buying another domain purely for free site submissions might be a good idea. I would be very interested in your cautionary tale as I'm curious as to what's causing so many domains to end up on that list. Might even cause me to re-think not listing sites that are on the list.
