This is an astute comment, despite "Arathorn" CEO of Matrix LLC's downvote ring pushing down the score. (Hey bud you know you can just read without commenting, right? Sit and listen for awhile)
ActivityPub has the same problem. Browse a Japanese MissKey server and it'll start loading yours up with questionable drawings. I turned off my server FAST
This is a big, big problem for federated software that I have not seen addressed or even frequently discussed. Arbitrary file upload by the public is not something small operators can reasonably allow on their servers.
Even large operators of non federated systems with controlled access like Facebook struggle with this. It's impossible to protect yourself as a server operator on Matrix or ActivityPub from malicious actors that want to use your server to distribute illegal material, and you'll be the one found liable!
Hosting any publicly uploaded content is a bad decision and a problem since e-mail. IRC and MQTT with QoS 0 do not have this problem. They have others though. At least criminals won't use them because of how easy is to snoop.
