Discord has a history of banning servers AND every related account. They banned the Trump discord several times.

If you use your account for any other purpose - create backups of your contact list or you will have no way to re-connect with people rapidly.

If you want a SuperStraight Voice Chat - go with Mumble, Teamspeak or Element/Matrix.

I'm surprised the r/SuperStraight moderators placed a server invite at the top of the subreddit without warning people of the potential risk and locked the thread.

This is strange. Be safe.
