When user is banned, do not allow them to follow the streamer they are banned from.
When a user is banned, currently they can still follow the channel. Some trolls use this to get past mods who are removing game spoilers from the chat by following, as this often brings up alerts and non deletable messages in the chat with the spoiler. A example of this has been seen often in The Last of Us 2 streams where they spoil the ending. This has happened repeatedly on a stream I moderate, and across multiple others, pre-emptive banning to try and stop them does nothing to stop them following.
