It's not just tester items (in case people who aren't testers are wondering). It's basically any new product, I'm not sure what the cut off date is. For example, my review of the Lovehoney dream rabbit is on my profile, where my review for the satisfyer pro 2 is not, neither were testers and both were submitted at similar times. Also, my review of the basics cock ring was a really recent secret tester and that is on my profile, because it's a product that been live for a long time.
My point being the glitch is with the date the product was put up on LH, not anything to do with testers.
