I am hopeful that spreading the news of this will make the tactic ineffective and "they" will stop bothering.
From Oath Keepers (and from Claire) comes a lawyer's advice on what to do if you are targeted.
However, I think this lawyer is ignoring the reality that the culprit is probably someone associated with the FBI or other feds to begin with. No one else really has any motive.
I have always been highly suspicious of any attempt to pin "child pornography" charges on those who are against the "government", or have made enemies in some local hive of enforcers, bureaucrats, or puppeticians. It's just too convenient and silences just about any support for the person. It makes their (former) friends turn their backs and join the witchhunt.
Use the information as you wish. Being informed should help protect you from such an attack.
And please don't forget.
