A while back patreon and itch banned a lot of NSFW artists under pressure from VISA/Mastercard. You know, porn comics and games. That kind of thing. I was reading about one creator who was forced to pre-emptively remove step-incest between consenting adults (who crucially were adults and also looked like adults) from his visual novel, after consulting patreon, so he could continue to receive money from them and publish on the platform.

Obviously, some of this stuff can be distasteful, but the tube sites are filled with porn of actual people and blatant incest plot lines. The porn industry also has a record of dubious consent, abuse, questionable ethics, rape, and child abuse. Apparently less of an issue for visa/mastercard, who continued to profit off those sites. IRC there was a recent complaint that VISA or Mastercard was still profiting off child sexual abuse material on OnlyFans, and were still recently facilitating advertisements on some of the bigger tube sites which had hosted CSA.

Pretty grim stuff, but I don't know what the solution is. I don't think forcing legitimate sex workers into illegality, because they can no longer use a bank account or credit card, is helpful either.

On a lighter note, back to the author of the visual novel. The author of the visual novel in question had removed all step-incest, but when he asked if he should also remove the bestiality, that turned out to be no problem at all.

Apparently there are some things money can't buy; but for cartoons of bestiality, there's Mastercard.
