I always had some "rules" when it came to in game interactions:
I am an adult player, please do not interact with me on a personal level if you are a minor, I will do only chit-chat about the game but nothing else. If you try to be inappropriate or anything else I will block you
I accept all friend requests
When it comes to horses or items, please don't beg for them. I can come to an agreement in selling them but no begging for things
I don't swap horses/objects
If I find horses withg inappropriate name I will report you.
