PTA Asked to Ban Misleading Ads for Illegal Housing Societies The Lahore Development Authority (LDA) has called on the Pakistan Telecommunication Authority (PTA) to ban advertisements for illegal housing schemes on social media. The LDA stated that several unapproved and illegal housing projects are being marketed through SMS, WhatsApp, Facebook, and YouTube advertisements. ALSO READ In a written communiqué, the LDA described how advertisers portray an attractive picture of their projects despite their legal statuses and the situation on the ground, which results in the illegal sale and purchase of files or plots. The LDA has received numerous complaints in this regard, most of which by people who had purchased land after falling prey to rigorous and large scale publicity and social media advertisements.
