I personally believe it does not warrant a nuke, unless some other French dude from lolca finds this thread and writes something along the lines of "ZUT ALORS DUDE HOW DID YOU FIND PICS OF MY GIRLFRIEND, I'll FUCKING KILL YOU WITH LE KNIFE".
Based on what I've seen, it's an entertaining thread. It doesn't contain any personal or confidential information, AND there's no indication that this is the guy's sister, apart from heartless himself. I'd say y'all got trolled.
In principle I agree. The thing is while I don't mind us trolling and being assholes to each other at all I still think the girl whoever she is doesn't deserve the esr retard treatment. Not that I'm butthurt or anything lol.
