So every lot has to be dealt with individually? That seems like a pain. The mod linked to above ("LBFRemovesocial" file) works if it is just sitting in your downloads folder, so maybe keeping it in there for a while will take care of it without having to do much? I hope so.

It's nice to have more than one option for removing it, all the same. If one doesn't work out, I can always try the other. So far, the LBFRemovesocial seems to be effective for me.
