A false flag ploy is a massive accusation that requires strong evidence. I agree this organization seems suspicious but I wouldn't hint at accusing them of intentionally uploading child sexual abuse material somewhere and archiving it with archive.is without a smoking gun.

I don't know why they first went to the host and not the entity itself but positive evidence is important. A false flag report wouldn't shock me (I've seen it happen many times) but I'll withhold judgment until further investigation.

It’s a reasonable possibility to consider given the evidence of bad faith, the factually incorrect claims, the apparent impersonation of a lawyer, and the apparent history of targeting using similar claims but “different” claimants.
