I swear to god if you have a problem with someone, block them. If you don't have a problem with someone, don't block them.
But please for the love of god, and for the love of at least mine and 5 bajillion other Fediverse users' collective sanity, if you have opinions or thoughts or actions you are going to take because of beef between two other admins, please just discuss them privately. I can't get this shit off my feed and it genuinely makes Mastodon / the Fediverse unbearable.
