Vandalism is the willful defacement, destruction or damage to property that belongs to someone else. It is named after the Vandals, a Germanic tribe that destroyed Rome. Wikis, such as Conservapedia, are constantly subjected to this due to the ability for anyone to edit. It's also quite fun! Although I admit there's probably better things I could be doing right now. Anyway, I hope you enjoy and I'm very interested to see how long my edits last.
By the way
Wow, your spam filter is annoying. Just try writing this article without once using the word v**dalise.
