Google is Amoral though. They do put value inside of niches, but adult links for instance, are still links and they don't consider them to be blackhat at all. Further a manual review could likely see the weight of inbound links. Clearly seeing that your spammy comments aren't what is providing the link.
However given the update a couple weeks ago, if you ofset the link profile enough for that link, you might be able to get it algorithmically penalized, lol.
Anyway, if you want the link removed, do real blackhat stuff, like doorway pages, shady redirects and stuff like that. Stuff thats actually very against googles TOS.
However if you want such a list that your after, just take any AA list you get, and then do a filter for negative words. Except remove urls NOT containing entries from - and then just use a list like I have here:

As for the list its self, you can scrape it, get some free here on BHW probably, search google for lists on a recent time frame, fiverr, etc.... If you want to buy long term lists I sell them in my signature, but if you want a one off fiverr or something is probably good. Just make sure they have some good feedback cause 90% of fiverr lists are Horrible, but there are some good providers on there.
