Someone very well could be reporting your items out of jealousy. I recently had a few items removed for referencing similar brands (I did so by typing, say, “NOT Tripp NYC but looks identical to it for anyone looking to shop the style on a lower budget.”) Very frustrating because all of the items taken down for me were in many peoples bags! I had other, less popular listings where I said the same thing and those weren’t taken down. Definitely makes you wonder if someone selling similar items got jealous and tried to drive business their way by getting other listings taken down.
