I am so sorry you went through this @uwu.I think you actually have to be charged with a child sex offence to be on the register here. Plus the girls he was messaging (that we know of) are of ‘legal age’ (which imo is a whole grey area as it is) so that’s why he got away with his disgusting behaviour. No grown adult man should be interested in messaging teenagers for sexual reasons or even to just be their mate, it’s wrong.
As I said previously I was groomed and then sexually abused by a 19 year old when I was 14 and I still ask myself to this day why didn’t my parents think it was weird that a 19 year old was talking to their 14 year old daughter. I’ve never actually confronted them about it because they will just say ‘back then times were different’
