Rather than revenge, perhaps focusing on convincing his parents on who actually did it should be his motive.

Why not both? *cue spanish music*

Then again, parents making assumptions because it's "always" his brother would be pretty bad as well.

parents generally blame number 1 and not younger siblings. I'd have thought my medic parents would have known it was my sister biting herself and crying saying it was me. they did not. my sister laughed and told them the truth 20 plus years later. their response? I probably deserved being punished anyway.

Speak for yourself. I am the youngest and I got blamed for everything.

Growing up, everything was my fault, because I was "older and should know better" even if I wasn't even around! My mothers reasoning was her 2 older brothers always caused trouble and she got blamed so it's always the older ones fault, never the younger. My sister, as a result, got away with murder, still does at almost 21!

Not always true. in my case, the younger (me) always got blamed first

Not necessarily. My drug addict brother made my high school years miserable I was almost always grounded for "doing drugs" and getting watched 24/7 by our folks because he convinced them I was either going to join a cult or do drugs so that they wouldn't notice the large amount of drugs he was doing.

You don't say?

Sorry, wanted to be Captain obvious. :P

there be a mutiny.

Why? to embarrass him for a watching porn? Sounds like such a horrible thing!!!

So is posting that his mother is a cunt and letting OP take the blame

Most people use private browsing for things they don't want others to know.

The point I'm trying to make is watching porn isn't embarrassing, most people watch it.

maybe letting other people know you watch porn isnt embarrassing, but having your parents know you watch porn (in their house !!) is a different story.

People if you understood OP’s FML he was using HIS own laptop. So all he would prove with a screen shot of browser history would show that he did it.
