If you can't take the heat, stay off the internet. A lesson many of us have had to learn the hard way, but one, if you take it from us, you can learn through the pain of the people getting roasted in this gallery. 

Take your lessons from these people, if you don't want to be on the receiving end of a dunk so bad that you have to change your name and move to another state, then maybe posting on the internet isn't for you. 

Sometimes the internet can be a nice and happy place, and sometimes it can be someone's villain origin story. This gallery is a collection of the latter. 

So if you don't want to find yourself on the wrong end of a brutal takedown, tread carefully.
