Twitter:
*I make a post at 9am and go about my day
*A racist replies with racial slurs at 9:15am
*Everyone sees the racist replies
*Everyone reports the racist replies
*Twitter mods take it down by 10am
*I check Twitter again at 11am, and never even see the racism!
Masto:
*I post at 9am
*Racists reply in such a way that only me, them and their followers, see the racism
*So no one reports it
*Everyone gaslights me with "I don't see racism here!"
