I love how, instead of blaming someone for not following the rules, everyone's blaming the site for having rules.
"It's just a joke on a credits page!" So surely it would be no issue for him to remove it and stay on the site? If he wants to continue translating on the site without mod harassment, then if it really is "just a joke on a page, no big deal", it's no big deal for him to remove it. If he absolutely refuses to translate manga without adding racist dogwhistles, blame him for being stubborn.
"It's on a manga with gore and murder and nudity and etc!" There's a difference between a character doing something in fiction and someone genuinely trying to convince real people of disgusting shit. It's why you're allowed to buy 'Lolita' but not 'Raping Children for Dummies'. A copy of 'Lolita' with a foreward saying "yeah child rape is actually pretty cool" would probably be banned from stores too.
okay there were times when Lolita WAS banned but that's getting off topic
then again, when I tried to argue on a chapter a while back, I had my points ignored and taken out of context, and someone said planned parenthood was as bad as organ harvesting, so I'm not really expecting much from this comments section
