I played in SL too for many years. It took a while, but I set up a business (a detective agency) and did pretty well. It was mostly drama from people with online relationships checking up on their partners and I got paid well to snoop.
Eventually, I met a young man and we became close. He lived in Nova Scotia and was part of a volunteer fire depart on Prince Edward Island. He suggested some other online games that we could do together: WoW, World of Tanks, and the other two related games (warships and aircraft). We spent a lot of time chatting online while playing and he became infatuated with me. He was my first stalker. He tried to track me down from bits of information I had shared. My next-door neighbor contacted me saying that a young man was in town looking for me. I freaked out and deleted all of my accounts.
About five years later, I decided to venture back into SL. New account, new name new look. I got settled in and started a business building cars and trucks. I bought some land and set up a garage and role-played a mechanic while building vehicles in the shop. About a month later, the owner of the sim stopped by and we chatted a bit. He said he wanted to introduce me to an old friend of his and the new town Fire Chief. It only took a couple of minutes of chatting and I recognized him. The. Same. Guy.
I used my snooping expertise to locate someone he claimed was his wife IRL. The information I got from her was that she knows him, but they are not in any RL relationship. He is 19 years old, lives with his mom, and does not work for the fire department. His fantasy is to be a fireman someday but he lacks the motivation/ability to actually apply.
So I closed that account too and never went back. I had so much fun there exploring my new-to-be gender, relationships, and interests. But I was not going to take any chances on running into him again.
