Though many companies advertise on Facebook, not all are as legit as they seem. CBS Dallas Fort-Worth heard horror stories from customers who bought clothing from these shady overseas sites and decided to conduct their own investigation.

The news station originally picked up the story after hearing from a Dallas-area blogger who bought a sweater from a company advertising on Facebook called Rose Gal. However, the package she received came with a rude surprise.

“When I opened it, this really rank smell came out of the bag, like mildew or food,” she said.

That station’s own investigation turned up similar results. According to CBS 11, which ordered four items from four different retailers, the journalists received a coat that was falling apart when it arrived, and one of the dresses they ordered never even arrived at all.

“Facebook prohibits advertisements that are deceptive, false, or misleading, including deceptive claims, offers, or business practices,” a Facebook spokesperson told the station when reached for comment. “We are investigating these claims and if we discover violations we will take appropriate action.”

Though the site may be committed to weeding out these con artist advertisers, it’s clear many still exist. Just because an ad is on Facebook doesn’t mean it’s more legit than the average pop-up, so be careful what you click.
