@anildash I didn't see this mentioned so I will: when a follower is scolding you he (it's almost always a he) is, IMHO, desperately trying to engage with you in the only way he knows how. Social media is used as a substitute for human interaction, and a bad interaction is better than none at all. I'm not excusing that behavior, just trying to suggest that something bigger is going on.
How to fix it? No idea. People who use social media instead of RL connections are in a bad place.
