Nope. I'm not federating to csam instances and then letting user individually decide if I'm going to have that on my server or not. No one has a right to store images on my hardware I don't consent to have there. Blocking an instance is not censorship because I'm in no way interfering with the blocked server's ability to function or of anyone else who wants to to federate with them. People who don't want to use my server under those conditions are perfectly free to start their own and federate with anyone they choose.
