Hold it! Who goes there?
Reason Answer
"I'm here to leave you a message!" Leave a message on my talk page.
"I'm a vandal and I'm coming for your page!" Ever heard of ClueBot NG? It'll revert your edits before anyone even gets an idea of what they looked like.
"I'm here to revert vandalism." Thanks for cleaning my page! I'll give you thanks whenever I can.
"I'm here to steal stuff so I can use it on my user page!" Help yourself... hehe...
"I just came here to glare at that edit notice." It's fascinating, isn't it?
