Yes, I think there are some things that should be censored, yet there are still many games about sexual abuse circulating on this same site, just as there were TONS of videos about sexual abuse on Pornhub, real videos and with minors. WE MUST be responsible with everything that involves sexual content, because it gets out of hand terribly fast.
Even so, I won't deny that there are games that did capture me more than I expected. "World Tamer" is one I'm playing now and it must be the NSFW game with one of the most interesting stories I've played, I would be lying if I said I wouldn't be sorry for that game to go away (although the premise itself is somewhat abusive, not to say something stronger).
In conclusion, I agree that games involving illegal acts or specifically sexual abuse should be censored. But not everything else.
