This thread has shown me a new tactic. If you want to break a NAP and surprise attack someone all you have to do is claim they were hitting you with anonymous spells. You send them a message saying "You are spamming ___ on me, it can't be anyone else, prepare to die!" and attack them. They can't prove they weren't and you can claim they're lying when they rationally try to blame someone else. Additionally anyone they blame will turn on them, because they know they didn't do it. No-one did of course, since it's all made up.

You can make this even more convincing and effective by posting about it on the forum too, ranting about them being sneaky traitors for spelling you.
