Pleaase add the feature written in the title as soon as possible. There is someone following me I don't want to see my games.
This feature should come immediately.
This is something block should do, but I don't know if it does. On twitter, block prevents someone from following you. https://help.twitter.com/en/using-twitter/blocking-and-unblocking-accounts
First of all, who is that bloke you're speaking of? Is this like a bully from school or an online stalker and that'd be either 1 of those reasons you don't want him to follow you, or is it something else?
Also the block button is identical in function to the ignore feature of Xenforo, so yeah it's pretty much worthless. You can still ban him if he comments on your games.
