Singapore - Lewd slogans and suggestive pictures used to promote matchmaking services are being axed from Singapore's newspapers and magazines, authorities said Wednesday.

Following several complaints, the Advertizing Standards Authority said the tightened rules aimed at removing the sleaze in dating promotions will go into effect in March.

Dating ads must be in text, cannot guarantee marriages and are restricted to the classified sections of newspapers and magazines.

Agencies accredited by the Ministry of Community Development, Youth and Sports can still run ads with pictures under the guidelines.

The organization said it is promoting "truthful, decent, honest and legal advertising" in the city-state. (dpa)
