Samsung Probed in Taiwan over Astro-Turfing

According to BBC, Samsung is being probed in Taiwan over paying students to anonymously attack HTC and praise Samsung products on technology forum websites. Samsung is not denying it, but has promised to cease these activities. The article states:

Samsung Taiwan said it had not been told about the investigation, however the subsidiary put a statement on its local Facebook page saying it had "ceased all marketing activities that involve the posting of anonymous comments".

Anybody think it is outside the realm of possibility that Samsung has been doing this to Apple?
