@eosxiomara - I read an article this morning about how up votes work, with a 5 minute delay (can't find where the article was now) before the "up-voters" maximise their earning potential if they upvote early and then other vote afterwards.

14 up-votes appeared after exactly 5 minutes, all at exactly the same time, none of which (as far as I'm aware) are following me or members of this community. So I think they've got to be bots of some sort. I'll be interested to see if the same things happens to my future articles or if it's a particular tag they're picking up. It's interesting that it's the main article that's being targeted and not comments.
