Spam
From WoWWiki
Spam (the computing term) has several definitions according to context but they're all derogatory.
In-game spam
- Sending an overly repeated message or large useless quantity of text in a Chat channel. Also known as Spamming. Players often "spam" the Trade channel with multiple copies of the same message in order to get their message seen.
- In-game whispers of "spammers" advertising gold-farming services, power-leveling services, etc. to a large number of people anywhere in Azeroth and Outland. Spammers may also utilize the in-game mail system as another medium of advertising their services.
- Repeatedly using the same spell or ability in combat. A fire mage might be accused of "spamming Scorch", a Shaman of "spamming Frost Shock" or a Druid of "spamming Moonfire".

History and origin
The term "spam" comes from a Monty Python sketch where patrons order from a menu where most courses contain SPAM, a type of processed meat. At several points, they are interrupted by vikings singing the praise of SPAM.
"SPAM" is a registered trademark of a type of processed meat. Lowercase "spam" is what we use when talking about pointless and/or unwanted text.
