A Spambot is computing device which through viewing this article has been accidently downloaded to your computer through a series of complex circuit thingies. Spambots are bots that spam you and your e-mail address with appealing offers on how you can increase your lifespan and find that perfect partner, for your lonely arse.
Spambots can also be found on wikis, irritating though they are. They can be stoppped at the push of a button. However some spambots imply dynamic IPs meaning they are vertially unbannable. So we use bots to stop them for us, see spamming our fair wiki is totally pointless.
