For those who still don't know how to work around the block glitch it's pretty much same as the bio one.
Always make sure you block the person you want to block in the first map you're in, if not in the first map, just rejoin the game.
Block the user you want to block, and rejoin again. Once you rejoin, they will always stay on your block list until you unblock them.
Pretty much the same thing as with them bios.
It needs fixing ofcourse, but I think kov is the only one that can, but the blocking does work if you do it this way.
