To be more transparent about server blocks, I have decided to follow the example of others and publish a list: https://github.com/Gargron/mastodon.social-misc/blob/master/README.md
That list is now linked from our about page. It also explains how different block severities work.
You might notice that bofa.lol is on the list. It's at the very least a temporary measure because our mods had to deal with a lot of problematic content coming from that place yesterday.
