How to deal with crooked people

[onlinebiker]

It just rankles me - as this turd is stll maintaining the ad on Craigslist. They can' t plead ignorance. They know they' re trying to rip somebody off "legally".

What i would LIKE to do is place an ad on the same page that would read " see this ad? This prick is trying to rip you off".

But that would probably violate the Craigslist UEA.

I understand how it rankles you.
He tried to rip you off.
If that car shouldn't be sold to anyone then it needs to be damaged in an observable way that would make it unsellable.
So many ways, but do you have the guts to do it?
If you get away with it you'll sleep better at night. 
Of course it's not really worth it because you could get caught.
But I think everyone of us should do something like that once or twice in their lives.
I have a different mindset to others.
I would consider it as giving back to the community and heroic. :-)

A spray can of paint - adding the words "rusted out" and an arrow pointing to the problem comes to mind.
