Moonpig has pleaded with customers to stop sending them pictures of their genitals.
The personalised card company has been inundated with explicit images from online prankers.
They wrote on twitter: ''Please stop uploading pics of your genitals to our cards it is against our ts and cs. (sic)''
The retailer were met with hilarious replies from customers.
One user wrote: ''Do you do pop-up cards? Asking for a friend.''
Another said: ''My dad is very apologetic but he's going through a bad time. No excuse I know.''
Moonpig replied: ''As long as he's aware now.''
The store's terms and conditions blatantly state that they do not allow pornographic or offensive material to be featured on their cards.
