Any hounders showing up at the door to hound publishers do so at their own risk. You could be nice enough to warn them of trouble ahead if they persist. They could get the cops called on them, or they could get sued, or both. And there are people around that would shoot them, pepper spray them, or sic a dog on them. In some places, it is in fact legal to shoot them if you have a No Trespassing sign prominently displayed and you warned them before to stay the fxxx off your property.
While I would not recommend shooting them, some people might just do it anyways. That is why they should not be poking their damn noses where they don't belong. Additionally, even if they do drag you back into the Kingdumb Hell, do they really want someone putting in field circus time and going to the boasting sessions, recording parts of these sessions, and posting them online? Or, what about the ones they successfully drag back to the boasting sessions only to have them taking notes (seems to be the thing to do), and then posting those notes onto an apostate board? And if they do get a judicial hearing, there are now recording devices that are no bigger than a pen (and can be hidden inside a handkerchief) that record 8 hours or more of audio. What is the value of having that recording posted online or used in court when you sue the hounders?
