Hm. OK, just brainstorming here; not sure if this idea is valuable.

Suppose you found a way to -detect- when someone was assembling your data? Like if all your public posts had little electronic watchdogs on them that reported in when they were viewed, and if a sufficiently high percentage of the watchdogs report in on the same minute, or if a sufficiently broad cross-section of the watchdogs report in on the same minute, then you know you're being scanned, and the watchdogs try to trace the entity doing the scanning?

And then if all the people who didn't like being bot-scanned cooperated and shared their information about who the scanners were so as to trace them more effectively and confirm the scanners' real identities? You could maybe force them to stop via legal action, or, if the gov't won't cooperate, just fight back by exposing the private info of the owners/employees of the bots?
