Just like a kitchen knife can be used by murderers does not mean that the kitchen knife manufacturer should actively monitor who is buying their knifes and go after the ones with bad intentions in my opinion
wrong
I’d just say to block those from federating to your own instances and stop giving those instances attention
that humanizes them, they'll feel like "i'm not allowed there but at least i can exist", which is a very dangerous precedent
other, more progressive, countries have done it: https://www.gov.uk/buying-carrying-knives
i support minorities so i would never report them
