Reddit permanently suspended all of my accounts because I said Ruth Bader Ginsburg is a cunt for not retiring when she had the chance. R/politics banned that account, and then a few weeks later I'd forgotten about that incident and commented in another post from a different account. That's when reddit permabanned all of my accounts.
I've been on reddit since August 2008 when Randal Monroe published this xkcd about it: https://xkcd.com/477/
