I feel that if any feature wants adding to the Mastodon platform, it's better-defined security controls. Accounts gets allow/deny lists and which tier they belong to: friends, friends' friends, server, (current!) federation. Each post may invoke same (at account level or lower, and it would cost the length of the allow/deny list).
I don't care who's popular. I care who I can trust.
@ElectricKeet At the account level or other, I meant. And the "cost" of the character limit, like CW's.
