i have built a simple firehose thing and hooked it up to some big open relays, and the funny thing is that about 1/3rd of the posts are garbage flooding in from mastodon (activitypub)
and an incredible number of the events that come through are profiles with rainbow flags and pronouns and neurodiverse/asd/adhd nonsense in it
but they all are from mastodon
hilarious tho... if i was running a big relay right now i'd not be accepting notes from this activitypub shit
