No one's going to censor you here. They can't.

The only real points of possible censorship would be relay owners who don't like your content living on their relays or media hosting services that don't want to host adult media.

There are solutions should either of the above occur.

For the first, just post to several relays. The chances all of them will give you the boot are slim. You can also run your own relay pretty easily as a way to back up your content in case you need to rebroadcast it to other public relays.

For the second problem we have Blossom servers. That's another whole thing to learn, and no need to dive into them right now. However, they allow you to host your own media without too much trouble, and then no-one can censor you at all.
