There is a page on Facebook (https://www.facebook.com/ProTraderBitcoin/) where they ask to send them Bitcoins and promise to give more than 3x return on the investment in 24 just hours. (See their plans below for more details.) They've looted a lot of people through this page and they are still active.

After you send them Bitcoin, they will ban you from the page the moment you ask for return after 24 hours. Also, the moment you try to expose them through comments on their Facebook page, they will delete your comment and ban you from doing so in future.
