As far as I'm aware it belongs to nostr:nprofile1qqs8nsk2uy2w529fs8n4tx60u7z553e4yx5dy2nxhw4elgjgawpqlaspz4mhxue69uhhyetvv9ujumt0wd68ytnsw43qz9thwden5te0v35hgar09ec82c30wfjkccte6rx8wx
And that's just progressives for you, can't really fix Mastodon since it's a shithole site.
Reddit would be this way too if it was decentralized, Discord is also like this.
Basically anything that is ran by sexually permissive people turn a blind eye to, or enable this behavior.
I think when Mr. Mostr developed the bridge he didn't account for this, he probably intended for only good Mastodon content to relay but the problem is moderating that relay is tedious work.
I don't think he's malicious with the relay.
I think he worked hard on the bridge but unfortunately the other side of the bridge is a tribe of terrible people.
And frankly if you worked hard on something it would bug you to destroy it, best thing we can do is find a way as a community to fork that bridge, and have it moderated possibly.
Leave the original bridge in tact, so no accusations of censorship can be made.
It's unfortunate but it's an apple to oranges battle.
