Don't post any of your personal information online and you wont have that problem.
I don't post my location, To even my drivers license ID to anyone on the internet. This guy has rammed into my system and stole information from me.
No, he didn't. The smallest bits of personal information can be used to find everything about you. Knowing just your real name online is enough to find out where you live, who your family is, ect.
He didn't spew that out, He spewed alot of my info out though.
You're in no real danger of losing anything actually important. He won't find your credit card numbers, your social security is fine. The worst he could do is subscribe you to gay research.
