I've dealt with them so much in MN. They run a few fake charities and a ton of fake political groups. They had something like five or so in MN alone. They basically just make up a bunch of lies to fund raise off of, and attack all of the legitimate pro gun groups. It is the same set of BS stories repeated in a dozen states.
https://www.facebook.com/trueiowagunowners has some info on them.
As to their effectiveness they intentionally torpedo pro gun bills to fund raise off of the failure. I don't just mean act like jackasses to drive away support, but they work to kill pro gun bills and then take credit once they pass.
Ben Dorr and I have had a lot of confrontations in real life.
https://www.sixbrothersdisasterrelief.com/about/ They pretended to help during a hurricane but never attempted to enter the disaster area. They just posed for a few pictures and videos and left.
They run some fake pro life groups, fake pro farm land management groups, about a dozen pro gun groups including national org. They funnel their money through a direct mail company that they moved from Iowa to Ohio.
