The newspaper often publishes news with oversensational and misleading headlines, and often using disinformation tactics to attack government opposition and critics.

On 16 July 2003, the newspaper published comments from media rights advocate Supinya Klangnarong, who said that the Shin Corporation, then majority-owned by the family of Thai Prime Minister Thaksin Shinawatra, had benefited because of favorable policies by the Thaksin government.

The newspaper was named as a co-defendant, along with Supinya, in a criminal libel lawsuit brought by Shin Corp. A civil suit sought 400 million baht in compensation.

After the Thaksin family sold its shares in Shin Corp to Singapore's Temasek Holdings, the company offered to drop the lawsuit on the condition that Supinya apologized for her comments.

Neither Supinya nor Thai Post had any objections, so the court withdrew the civil suit.
