Hi, copywriter31. Seeing a hubber name in your stats doesn't mean they have published your article, it just shows they have read it. Most reader stats will come under hubpages, but sometimes individual names come up. I think it depends what route they took to find your hub, I did read about it a while ago but forget the answer. So they are not doing anything apart from reading. If someone shares your hub with their followers, again it's only you who has published the hub. They get a small percentage for sharing, which comes from hubpages' share of revenue and does not reduce your income if someone reads it. It's a good thing because your hub has more exposure. Hope this helps.
