As long as they don't correct it, then MAYBE! Again though, companies like Blue Coat who are arguably the market leaders in things like content filtering, wouldn't be there if they were arbitrarily blocking these sites without correcting wrong ones. Just a thought.

Several items to question here. Where did these lists come from? Did the author manually track down sites to find out which ones were specifically miscategorized by the specific vendors? Seems pretty unfair if you're only going to target two vendors instead of taking this ENTIRE list (the one used for Smartfilter and the one used for Blue Coat) and test them against ALL major vendors in this market space and report on that. Otherwise, he's just trying to create anger around two specific vendors (probably because they blocked his porn and he's upset with them). Did any of these websites host questionable content that WOULD have caused automatic rating services to trigger it as porn at any time? Without contacting the owners of each of these sites and getting them to admit that their sites were indeed hacked and used as hosting services for nefarious purposes, you're not going to know. A lot of times content can be hosted on sub-sites that aren't linkable off of the any of the pages. So again, how would he know if things weren't awry? He seems pretty misguided here, while trying to put on the show of "knowing" what he was reporting.
