If you can show who's running those lists, and their names, sue them for damages. Garnishment is very much a thing.

Admittedly, attacking others in a system that features money as a signifier as status/power isn't usually wise. But given these people are trying to use blacklists as a form of power, this can be used against them. At least if the threat of monetarily loss isn't realized, the fact that you're willing to drag them into court will... expedite any issues you have with being on that list.
