Yes, it can change any time and you can follow what's changed. It's also open to appeal to the company and I have seen mistakes corrected.
My point is there is no secret agenda to bring up a content that supports one view. What Turkish gov wants to achieve is that, taking down the content they don't like. They have taken over all mainstream TV channels and you wouldn't see a line of critic on any channel, if you do it's quite likely you will not be invited to debate next time.
