These pesky fake Instagram impersonators are getting sneakeir and more creative by the day, you just don't know if anyone is really who they say they are on the other side of the screen nowadays.

Lucky for me, no one here has tried to impersonate me and shill cryptos... yet. I just really don't like cryptos.

Also,

... while simultaneously blocking the authentic profile whose pictures they are misusing. This cuts off the possibility of contact with and being seen by the authentic user.

This is why I think 2 way blocking as implemented here is a bad idea, because it really opens up the block function as a potential avenue for abuse.
