yes but at the same time there are good reasons to keep things NSFW, it is a balance. If everything was allow like steam did than you would see scammers, AO rated games, more realistic gory games than Mortal Kombat, questionable things in NSFW, etc.
what you asking is having people not be ignored but that is impossable since that leads to fights. you can not change people minds unless you somehow did. And sometimes people push the question someone ask for into uncomfortable or unneeded infomation.
itch.io rules are fine it stops the fighting or gang-ups, block button to not see and reply back/get reply to user is also ok.
