Yeah, that is very varying from instance to instance, I try to keep outright porn completely out of mine, for example, but allow non-sexualised nudity (within reason), both for my own server and content I federate with. Others, like peertube.wtf don’t allow porn on their server, but allow it in the federated content. Others again just outright ban NSFW content altogether.
Haven’t had an FP6 in my hands yet, but I’ve been using FP since the Fairphone 2, am currently using the FP4 and besides the ethics in sourcing their materials and manufacturing (which they genuinely attempt to provide, and while there is no ethical consumption in capitalism, there are still degrees of fucked-upness.), I do enjoy the repairability, longevity and long-term support. They are also decently supported by de-googled-android and even pure Linux phone operating systems, if you want to experiment there, and come without a lot of bloat that nowadays is ubiquitous with most smartphones.
