Yeahh something like " are you sure you want to block .... "
Or something?
I think it would be nice to have an "are you sure?" Message before we block people

Especially on mobile, since we accidentally click something a lot lol
And the ignore button could be 1 of them

I just found out today that i actually block 3 people that i didnt even know that i ever block them

@Raxton: this is an A idea to have, and it has happened to me me as well by accident.
