Though quoting scotty86 below, this is a SCAM post that's directing you to buy fake tokens:
!!SCAM!! Be aware! This is a scam! Do not trade on EtherDelta POA token from the link in this post!!
Some shit head (sorry can't find a friendlier name for such a person) made his own "POA" Token (Contract Address: 0x9e8df8fD7c6c724880E2D73D8fAF7Fc7fF98c5C4), but the POA Token from Oracles Network has the contract address: 0xc8fe4a2d14Cb9027Ef955D15E8BF811a6DB0Bf74
Do not use the EtherDelta/"Buy POA now"-Link from this article!! The POA token from Oracle Network have not been released so far. Always use https://coinmarketcap.com as entry-point to EtherDelta, if you want be on the safe side.
