Yes, I was a Senior Manager at Tokbox I actually spent a great deal of time moderating or monitoring public posts, so I was aware of the underlying problems with them. Like any web site offering something public, such as a blog or forum, you are going to have issues where a few people wreck it for the greater community at large (posting bad content, for example; the video aspect makes it more complex than simply text comments).

I would expect some changes soon:)

Even though I recently left Tokbox, I do know that there are changes planned for public posts (the company realizes that they pose a problem and challenge); I can assure you the issues with the public area will be dealt with.
