Just to give you guys a heads up, from my experience, he uses the "Forgot password" feature on sites a lot. Make sure your security questions cannot be guessed by know personal information (Your pets name is a very bad question, you might tell someone that without thinking, or the info could be on facebook, which is a potential leak of info). Also, google yourself and see what information is available, if you have an uncommon name like me, you'll potentially have several results.
You should also set your facebook privacy settings the highest they can be, I had a bunch of info revealed about me through that.
Also to the topic, so far I have not seen evidence that Poiuyt, he just knows how to gather information and use it.
To anyone trying to be his friend, don't do it. I was trying to be nice to him and he ended up trying to get into my email and gathered information on me. You shouldn't trust someone who does these things to other people.
