This was posted a few days ago (02 October) on thaivisa.com, but it apparently applies to ALL web sites, not just thaivisa.com:

Bangkok Post bans Thaivisa from using its content

BANGKOK (thaivisa.com): -- The Publisher of Bangkok Post, Post Publishing PCL, has informed Thaivisa.com that they have joined the "Society for Online News Providers, (SONP)", and their policy is apparently that RSS feeds are the only way for other web sites to republish news articles.

Given their request that no content be published on ThaiVisa unless as an RSS feed, which is an automatic feed with no commentary, Bangkok Post articles can no longer be published in any ThaiVisa forums from now on since the forums are not an RSS feed.

...

For legal reasons, and to protect the website and its members, Thaivisa.com must comply with this new policy and urge all members to avoid all Bangkok Post content, advising its members to find alternative content instead.
