Same thing happened to me when I wrote a review of a company on Trustpilot: they asked me for proof that I was a customer and I told them to take a hike (well, actually I took a hike, because I never responded). Presumably the tenor of my review caused them to think I was gaming the system, when in fact it was an honest review, and not particularly fawning or critical, either.
In any case, I have absolutely no incentive to engage with Trustpilot further, on this matter or any in the future.
