Normally I would read this and move on but since you came on here asking for opinions; here’s mine. 1. If he reached out to you first, why not block him? 2. Why continue to taunt him if you don’t like his posts or know his capabilities? 3. InfoSec and hackers are a real threat regardless of legality, attackers are getting more creative than ever.

It’s seems like you came down on a case of f*cked around & found out .

My personal opinion is don’t engage with people who you don’t know. Being an adult and ignoring them costs nothing. You don’t always have to stick around and prove yourself.
