Performance

gollark: Even though it was of course totally true.

gollark: Anyway, this whole situation was contrived completely to try and discredit us being the same. Remember how Lemmmy first came about?
gollark: Their username says so and they're me so they know things.
gollark: They never said anything about this but never denied it, fearing the consequences if this got out. But I trust you to make your own reasonable choices with this information.
