Any method that image hosting services are using now will work the same with a blossom server. so you could either manually moderate or run an AI script over the images and remove any offensive images.
That said I don't expect there to be many public blossom server. most will probably be either a personal server (like my cdn.hzrd149.com) or operate based off a whitelist of npubs (or an npubs friends list)
oh man. Blossom can change the world. should be included with relay software.
There is already a few server implementations https://github.com/hzrd149/awesome-blossom
Although none of them implement the WoT permissions yet
i'm working with a massive data import right now
it makes me think that keeping the raw events separate from the filter search index would be a massive performance boost and doubly so for bulk import, but generally for heavy write load
a blossom store could be a perfect place to put events
