The thread goes on forever, but the short version is a member of the forum posted his stolen item, an A-Spec TSX bumper taken from the parking lot of his work, and other members noticed a similar style lip ended up with a person on a different forum. This is a minor coincidence until they realized the same alleged thief/member had inquired about where and when the victim worked.

This would have all ended with little-to-nothing happening until the suspect started reposting on the forum, claiming it wasn't him, and inviting people from all over the world of Canadian forums who had been scammed by the same person. The likely scammer even signed up for a different account, from the same IP Address, to defend himself.

You'll have to go through the thread to see all the humor and the thread is now closed because too many people were making too many threats against the could-be thief. Unfortunately, these things sometimes turn vigilante so we're happy to see the forum members turned to the police instead. Hat tip to Saad!

Alright, after reading a ton of threads on welding up gears for extra traction, i went ahead and welded mine up.
I put the third back in and went to pull out of my garage, and I just roasted my clutch. I figured that maybe there was some slag left in the bearing, so i dropped it in 4lo and lo and behold something broke loose.
MY FUCKING DRIVE LINE.

I'm really pissed at all this BS talk. I welded my junk really wel. And now my driveline is twisted up like a damn pretzel.

You are all a bunch of shit talkin Jerks.

What the hell did you all do differently?

This troll has used several cunning techniques to lay his trap. First, he's carefully chosen his quarry, Pirate4x4 is home to some of the most no-bullshit off-roaders and rock bashers on the net. It's fertile ground for a sneaky troll. Second, he's taken a well-loved and cheap modification technique referred to loosely as "welding the differential" and turned it on it's head, creating something nonsensical and then displaying outrage at the darn thing for not working.

We'll explain. Normally, welding a differential means you permanently weld in place the spider gears in a diff and create an el-cheapo locked differential. If you want to buy a real locker later on it's an easy replacement and it's a good way to get mud bogging when you're doing it on the cheap.

This troll has not done that. Instead, he's welded the pinion to the ring gear which creates a differential-shaped paper weight. He even supplied a second picture to prove his point and then called the forum a "bunch of shit talkin jerks" for providing the information he misinterpreted. To the credit of the forum, the primary reaction was to call the troll a moron, but there are a couple members who fell for it. Remember to keep your eyes peeled, forum fan-boys. Without proper vigilance, you too could fall for this wily troll trap.

What happens when a troll purporting to be a 2003 Mustang Cobra fanboy wanders into GM forum territory and drops a bombastic tribute to his claimed chariot of choice? Trolling that reads like a Chuck Norris tribute novella. We've seen this type of character before, but never for the '03 Mustang Cobra. Obviously it must be because we didn't realize the weakest part of an '03 Cobra's drivetrain is the driver's neck. Read on:

Needless to say, a bunch a guys on Norcal LSX forums, a place dedicated to the love of the General's LSX motors, were not terribly receptive to this... this "Cobra driver" coming into their home turf and laying down a list of reasons "03 CoBRA ownS YoUr FACES (as a whole)." This is a variety of trolling we like to refer to as "being a dick" and this is a particularly excellent example. [Norcal-LSX]

Forums being tight-knit internet communities, it takes a certain caliber of bait in order to raise the ire of members. The following is an excellent example taken directly from Mustang Forums and leads off twenty five pages of responses ranging from outrage to nod-nod wink-wink amusement.

I'm done with this car!
My car was idling like crap the other day so I figured since I just got it, it may have been awhile since anyone changed the oil out. I decided to go ahead and change the oil. I used Mobile 1 synthentic oil like I was reccomended on here. Anyways, I drain out the oil and noticed it was extremely dark and even after 10 minutes of draining, it was still coming out. I decided to go ahead and flush it to make sure all the bad stuff got out. I hooked up the hose, ran water through the engine, started it up and was waiting for the water to come out clean (The engine never went above idle so I was told this would be ok). Anyways, About 3 minutes into this, then engine starts shaking and shuts off. I figured it was all cleaned out so I plugged it up, added the oil and figured I was ready to go. WRONG! The car won't freaking start now. This car has been nothing but trouble for me, I think I am done with it.

Bravo sir, that is some Grade A trolling. Adding insult to injury, the poster claims to have done this to a 1994 Mustang Cobra, which, in the Mustang community would stand as a grand offense. Heck, it would be a pretty serious offense here. As any good troll does, this one stokes the fire with earnest responses. Head over and enjoy the firestorm this guy created. If nothing else it serves as a hilarious warning to be ever vigilant for troll kind. [Mustang Forums]
