Why I can't follow this user?

@ConvertToRGB well i guess you can still watch his games, just keep watching for it

@ConvertToRGB
Use this link to watch their games: lichess.org/@/ElTalBot/tv
That's the only way you can follow them when blocked.

@ConvertToRGB , i can follow that user so that means that it’s either you got blocked or that it’s a glitch.
