It's tricky with guppe though, as it allows spammers a vector into instances they have no business being federated with. The #mastodonforharris hashtag has been taken over by users abusing the mutual aid group, and whenever there are apam attacks on mastodon this is how they reach the entire network rather than individual servers.
So it does confront a fundamental problem with how Mastodon works. But as long as they're there, I guess it makes sense to use them for legitimate uses as well.
Ah, yeah, that's messed up.
I'm really happy Mastodon takes their time todevelop new features instead of rushing into things. Makes me hopeful they'll get it right.
