Following its many shake-ups to online ads over the last few months, Baidu has announced yet another change to its advertising policy. Recently, the Chinese company decided to halt any promotion of cryptocurrency on its network, including Bitcoin platforms. Whilst the reasons behind the termination of the ads is yet to be confirmed, it is reported that the decision may be due to the high volume of scam sites fronting as cryptocurrency pages, on Baidu's pages. If this is correct, it may be planning to create a filter system that would let state sanctioned and legal sites through. This would happen by allowing popular, well-known Bitcoin platforms such as Circle or Bitpay through the filter by way of a verification process. Meanwhile, users of the sites have said on forums that it may have been a government requested move, which would set a dangerous precedent for Bitcoin and other cryptocurrencies
