Is is true that HumaneWatch's David Martosko engages in some really sleazy tactics to foil animal protection?

[Concerned Citizen]

I read on Humanewatch.info he was pretending to be a vegan to spy on activists and also acting as an "agent provocateur" on Facebook - trying to get animal advocates to commit acts of violence so he can use their actions against them.

He's a world class wanker. Hero to animal abusers everywhere. Will say and do anything for a buck.

Martosko, is a lobbyist, but unlike most, he keeps his clients secret, by hiding behind a 'non-profit' group.
There are legal loop-holes in the non-profit category, and he has manipulated them to hide his true intentions.
The reason for the attack on the HSUS is simple..he represents meat-packers and livestock producers and huge corporate agricultural conglomerates who do not want to spend the necessary money to meet humane standards which the HSUS has been trying to get them to do.
He is worse than sleazy...he labels 'terrorist' anyone who is interested in a more humane treatment of animals.
He is also very personally disordered..for example, his organization spent years smearing Mothers Against Drunk Driving, while at the same times he was arrested for doing just that.
There is proof of this on the website previously mentioned.
He spreads his misinformation by posing as many different people on social networking sites, giving the impression that there are many more people who are 'with him' than actually are.
A very sorry, sad, and bad intentioned person...
And it's animals who suffer from his actions the most.

That's what I heard. He and Breitbart should get together, they have a lot in common.
