I think that is the worst sin for those posting on PB.

I had a similar experience when I posted on my experience with the IMUSA aluminum mug. I had been using one for nearly two years and mentioned that in a post. I also included a photo of my weather-beaten modified mug. I suspect that since my experiences with the mug pre-dated that of the OP (the moderator and purported discoverer), my post was made to disappear after about 2 hours of residence on the forum. I have not posted on PB since and seldom visit the site; TLB is both more congenial and more informative.
