I answered a question on Tablet K with a link to a blog. It was erased due to "stories heard through the grapevine".
However, the blog post I linked is a first-person account under a real name. The person is easily verifiable online. This is not a story heard through the grapeline, but an Eid Echad account who is just as believable, if not more so than a kosher symbol, and thus halchically valid. It should not have been erased, as it is not a rumor but a first-person account of someone who experienced tablet-k's unreliability first hand. I believe the answer should be restored.

Regarding the ability to execute his policies:
Just Call Me Chaviva (AKA Kvetching Editor) describes when a Tablet-K certified institution served CATFISH and no response was taken!
It turns out the hecksher is Tablet K, the rabbi is Rabbi Rafael Saffra, and the kitchen is only open for kosher food during the summer. This means that the folks running the kitchen have only 7 prior weeks from summer 2008 under their belt, are not trained in kosher cooking, and that -- perhaps worst of all -- there was no mashgiach in the MEAT kitchen. The rabbi visits the campus at the beginning of each summer (which means he's visited all of twice), and gives all of his advice and guidance on kashrut from a great distance. Basically, Tablet K took the money and ran, which appears to be their M.O. We also found out that the guy who makes all the food realized, almost instantly, that the fish wasn't kosher. Making it fishy (har har) that he even made the product. I'm guessing this is why it was packaged separately for our consuming pleasure. The campus rabbi was less than excited to help or discuss the issue, and he was of no help in the situation. I expressed a desire for the kitchen to be rekashered -- that was the only way I'd eat anything out of the kitchen. I was told that it WAS rekashered (though without supervision by ANYONE). The rabbi didn't offer to rekasher, and neither did the school.
