That's a really interesting question. I can't answer that directly, but I did know a person who happened to be stalking me. Weeks after I told this particular person to sever all contact with me, he popped up as a referral of mine here on HubPages (which meant he'd either read my blog or profile here on HP.) As the weeks wore on and the stalking got worse, I'd pointed out that he'd join HP under me and he questioned the ethics of hubpages referral program and accused me of stealing from his company on the basis that he'd created the account for his company and that I was set to earn referral $$ from him. He didn't understand that the $$ came from HubPages part and I really didn't want to get into an argument with a person I wanted to leave me alone.
Here's my question to you: Is referring a person, without their knowledge, to HubPages ethical?
