I believe that "Fanboy's Annoyance List", which is one of the blocklists mantained by EasyList (and can be used in uBO, ABP, etc.), is supposed to suppress newsletter popups and similar junk.

Their coverage is not nearly as complete as the main lists' coverage for run-of-the-mill web ads, though.

If you feel so inclined, the official method for notifying the maintainers of content missed by the blocklist is the forum at https://forums.lanik.us/ and it appears they update the list every 7 days or so.
