Try to create an account lightly. Don't use a big name like TSMAAL-Illogicopedia-GEN-MOA-2099-BLG-266A-freeholiday-nonhindley-tsm1938-btv-newans-9182. It's too long anyway. Use a name like Screencat0248 or something. Then, you must begin the vandalism. A good idea is to make a few good faith edits before the vandalism begins.
Step 2: Types of vandalism
Page blanking is a typical vandal action, but could easily lead to blocking. You know, this is why pages are protected.
ejhruewjehrgekrjh eeywquw see my kiwi cat, for tomorrow: See I did that. Theory of taxation is important. This is common, especially with Uncyclopedians.
Go see the cat videos at screencat.web/internets/nicesite/nicesite1/site1.shtml. It works I guess. Don't you agree.
Step 3: Warnings
Soon the anti vanduls will leave messages on your talk page. Ignore them, try to emit a good response, like some sort of sarcastic quip.
Step 4: Infinban
This will happen. If it happens, don't worry; log out, wait until you change IPs (static IPers, sadly, are out of lock) and then create a new account, whether AGF or vandal.
