Catfishing
From MgmtWiki
Full Title or Meme
Using a Pseudonym to create a virtual Identity on the web. Often used pejoratively.
Context
While the term Catfishing is of recent vintage, the process of pretending to be someone you are not is as old as records are kept of human history. Jacob pretended to be his Brother Esau to cheat him out of his father's blessing.
Problem
While the use of Pseudonyms is encourage to help you protect your privacy, it can easily grow into Catfishing if the pseudonym is reified into a life of its own.
