A kind of animal that the ancients catalogued under many heads.
A serpent or monster in the lake or marsh of Lerna, in the Peloponnesus, represented as having many heads, one of which, when cut off, was immediately succeeded by two others, unless the wound was cauterized. It was slain by Hercules. Hence, a terrible monster.
A southern constellation of great length lying southerly from Cancer, Leo, and Virgo.
Monster slain by Heracles. For every head that was chopped off, two grew back in its place.
A grotesque creature with at least seven heads who dwells in swamps and other waterways.
A serpent or dragon with five or more heads. In Greek legends this creature could only be defeated by cutting off it's heads and then burning the neck. If this was not done where one head was cut off two more would grow in it's place. Hercules had to defeat this monster in one of his 12 labors.
Heracles' second labor was to encounter the Hydra, a nine-headed serpent, which would grow back two heads for every one that was severed. Every time he clubbed off one of the heads he cauterized the stump so that another could not grow. A hydra is a polyp with a cylindrical body and tentacles surrounding an oral cavity and it has the ability to regrow itself from cut off parts. A hydra can also be a destructive force that does not succumb to a single effort. The Hydra is a constellation in the equatorial region of the southern sky near the constellation Cancer.

The id's get banned, but this frustrated individual or group of individuals just gets a new email account and joins again under false pretenses.
