SPA vs SPA
The Spy vs Spy drama turns up on Wikipedia as SPA vs SPA, where SPA variously stands for Single Purpose Account or Sock Puppet Account. But because it's so easy to create sock puppets on Wikipedia, the embattled characters turn into micro-armies of warring factions.
Most of the SPAs get wiped out, but some SPA vs SPA dramas turn into epic battles that last for weeks, months, or years. The genre has captured the imagination of more than a few observers and critics, many of whom chronicle the more amusing cases on Wikipedia Review. In at least one case, an SPA has been outed as a real cloak-and-dagger character with alleged connections to Britain's MI5 and/or the US CIA.
