Years ago, I created this list of non-Japanese animated television series aimed at adults:
https://www.imdb.com/list/ls074779977/
The list is, by far, the most exhaustive such list in existence. It encompasses everything from the extremely well-known (The Simpsons, South Park) to the ultra-obscure (Two Posh Old Men, The Esperanto Family); several of the titles on the list weren't even listed on IMDb at all until I added them to the database myself. It is the sort of thing that only a true sperglord could compile. 
However, I am sure that it is missing some titles - especially since I was, obviously, out of the loop while I was in prison. Shortly after I got of prison, I added a shitload of titles to it. Please tell me if you see anything missing (and what you think of the list). 
(Previously, I posted a similar thread on here about my list of disturbing films.)

They wanted to get picked up by a real studio but soyteens have probably inadvertently ruined that.
