"There are some real psychos out there. If you haven't encountered any, consider yourself lucky. I knew of a guy once who tracked down real-life details of people he fought with online, called their relatives, called their employers, and generally harassed them until police were brought into it. Not a situation you want to be in! "
Nice! I thought everyone had way too busy lives, nowadays :D.
On a more serious note, I'm a paranoid person at heart, so I knew the only way he could have found out anything about me would have been by hacking into the website's server, getting my IP address, and then hacking into my ISP service provider's server (if I understand all of this right which I might not :D), so felt reasonably safe.
Then, again I have to admit the situation was just too tempting, and I couldn't resist the temptation...even though nothing happened Ill hopefully learn from that for the next time, and will just point out very politely, that the person is wrong :-).
Today, I just resisted the temptation to argue with an idiot on the internet. My success rate at this has gotten pretty high over the years :-), it was just that one situation hehe ;)
