Endmyopia:Vandalism

"PENISPENISPENISPENIS"
I say! That was rather intelligent of myself old chap.

Vandalism is when editors insert rubbish into articles.

An example of vandalism would be deleting the Pseudomyopia article and replacing it with the delightful little sermon that our friend to the right came out with.

If you're an admin, just block the vandal, and tell them why they were blocked on their userpage.

If you're not an admin, feel free to have an edit war with them until an admin gets around to blocking them.
