I'm really sorry - you're one of the good guys and don't deserve this.
I might be an old guy, but I like to think I'm not creepy, and I'm certainly not that guy.
It's sad that we all have to be careful with anything we do online. Out of habit I don't use my real name on Hive, never use real data for things like birthdays, and don't give out anything that could provide a location closer than the large town I'm in (including making sure photos around the hose don't show enough landmarks to geolocate by). At least with Hive the properties in images are scrubbed off to eliminate location data etc.
All I can say is that while there are some awful people out there, the majority aren't. Be careful, but don't let it break you.
All very good advice thank you. It is always best to be safe and careful with these things.
I have blocked that user at least.
