So, you blocked someone. Obviously when you block someone you don't want to have any interaction with them, be it on their main or on their side account. But what if you only know one of their accounts and they'll still be able to interact with you on their side while you'll have no clue who they are?
There's no way of knowing if a user has a side, and then what their side is, unless its stated in their name or bio. And some users are secretive about their sides just so they can continue to pester you when you block their main.

I'm not sure if you're allowed to ask modbox what someone's linked account is, but if you are that's still kinda a hassle. And if someone you blocked contacts you on a different account, that's blok evasion and you can report that, but again that's too much work when you just wanna be left alone.

So an idea:

When you block someone, the linked account should automatically also be blocked.

It would make everyone's life a lil easier, just be rid of someone in one click instead of having to figure out what their other account is. There'd probably be less block evasion issues too! I mean it's a win-win situation right?

I'm bad at wording this stuff, but I hope you will agree and support, or make suggestions how to improve on this idea.
