My newest invention is stupsbot.org, a simple website where you can enter a Twitter nickname and my Twitter bot (@Stupsbot) will poke them like on Facebook. 
I have read that people need an easy way to “opt out” from automated mentions. Now my bot’s profile says “block me if you don’t want to be poked” as it doesn’t do anything else. Is that enough or will I have to create a complete database of Twitter user names which don’t want to be poked? If so, they would have to log in with Twitter so I can verify that they’re really themselves. I don’t think this would be easier than just blocking the bot…
Do the rules accept “block me” as an easy opt-out?
