Against the security of the kingdom?

Absolutely Bangkok, a website that I would hardly associate with subversive content, was recently blocked by LoxInfo.  There is a fascinating account of the episode available here.  With the current appetite in Thailand for “crackdowns” of various sorts, this is unlikely to be the last time that a popular English language site is targeted by Thai Hotline and its ilk.  But the question remains: why was Absolutely Bangkok blocked in the first place?  Any theories?
