Someone who uses dating apps such as Tinder, Buble, Plenty of Fish, etc. to either promote their Only Fans, sell their "content", or offer sexual services for money. They often try to get you to add their Instagram or Snapchat account. They typically unmatch with you shortly after their solicitation.

Dave: "As you should, The Hub is free!"
