Folks on the toad.social server can add the 
custom emoji to their profiles (or posts) to identify themselves as part of the toad.social community. The opposite of a blue check, it’s available for all in our community, and stands in opposition to blue check elitism and right-wing frog-centric memetics. 😉
It’s a custom emoji… use the code : toad : (omit spaces) to place it anywhere!
@davetroy Ahhh... thanks!
@trinka to use it, you need to be based on the toad.social server. Unless other servers pick it up, which is unlikely. :)
