But do you believe the "backfire" was fair? He wasn't the type to to try to hurt someone's rep by posting their name and family members' names, along with lies and accusations just in hopes that it's searchable in google and will embarass him one day when an employer or even friend searches his name.
Some people have a crazy streak in them. Squad always managed to push buttons, and he crossed the wrong person (in this case, it was Derek).
I've never been one to give out personal information online, especially since the Mower incident; that took things to an entirely different level. If someone I've befriended asks for any type of info, I'll either ignore it, give them a newly created email account, or lie. Even if they're that good that they can get around any/all of these, it's still more work and hopefully it will deter them from whatever their intent is.
Squad pushed buttons, it was his thing. He loved to do that, and often times he went too far with it after he had "broke" that person. But he wouldn't let up. On the 'net, people get caught up in shit quickly and let emotions of being "owned" and whatnot get to them.
Squad pushed and with all the factors above, someone pushed back. I don't entirely agree with what happened, but when you play with fire, you're bound to get burned.
