In another site, my question about upvoting Are other people also seeing an increase in upvoting recently? received this answer:
It was me I've been going around and up voting everybody like crazy and I can't stop myself. I'm so addicted to up voting and I think I need to get help before my up voting gets me into trouble.
I've just experienced an "upvote storm" five minutes ago here in Earth Science SE, coinciding with the same user having been active five minutes ago as well. I'd like to convincingly inform the user that this practice is unacceptable in all sites and more than bothersome to the one on the receiving end of the storm. How best to do this decisively?
