See Happy Tree Friends. (The following definition is based on the cartoon's forums.)

A crazy place where spam runs rampant, furries talk about how they want to sex up the characters, emo and goth 8-11 year olds post about how they want to commit suicide and the occasional smartass enjoys flaming people on a totally unrelated topic. Also common is a thread which argues on a cartoon character's freaking gender.

The ratio for on-topic posts to spam is 1:12. Most on-topic threads aren't worth reading anyway because they'll turn into a flamefest within 5 posts.

In some cases, the boards have actually been used as an insult on other message boards. (i.e "Go back to the HTF forums you scum!")

If you like Happy Tree Friends, steer clear of the message boards because it will warp the way you see the show itself.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
