I don’t think the thirst posts are trolls, but I do know what you mean. One of my top priorities this next month is adding NSFW filtering to the app to allow people to toggle that sort of content on and off.
By the way this isn't a snarky rhetorical question. I wonder whether people do experience censorship more than the built-in preference filters on BlueSky.
For one thing, BlueSky blocks NSFW images from being embedded in RSS feeds, so I have to use third-party services like https://bluestream.deno.dev/ to generate RSS feeds which embed images in my RSS reader.
On Bluesky they just apply a label and users are free to toggle it as show/warn/hide. At least, this is what I've personally experienced using the site.
