TinyTeaCupJr it depends on the officer on duty. some act professional, a lot of them dont. police is far from perfect in our country too. but it's still better to report them to the police, than just to the officials of the websites and apps they are bothering you at. even steam recommends to do it
in the end all criminals get busted, no matter how long they try to hide. you should keep reporting them to the authorities, one day they will get what's coming for them
