can あなた block someone?

Lmao one of the reasons I don't come on as often anymore is because the block button is basically useless. All it does is forwards messages to the trash; people あなた blocked can still send them to you. They can also post on your ウォール if あなた post on any of the club walls. There's literally no way to completely block someone from interacting with you.

Yes, I think it is. Whenever あなた receive an Eメール from that person and open it, you'll see 4 options. One of them is 'Block User'. Hope this helps.
