ChatGPT 4.1 suddenly keeps rejecting

Today ChatGPT 4.1 suddenly keeps rejecting me, despite my attempts to change the prompt multiple times. The conversation was just fine with full explicit details before and suddenly he said he cannot continue with those kind of things anymore. This is actually depressing as I rely solely on 4.1 for NSFW and now they took it away as well. Have the railguards been tighten recently??? 😡😔😭💔
