I would guess it's bots that are upvoting you, you could check the list and go through the upvoters.

I just checked my latest posts but do have the same experience. Unfortunately I always have more views than upvotes, so that's still something to work on ;-)

EDIT: Yeah, I done it as well. One of my posts now has 9 votes and 8 views, and 1 of these views is me. It gets stranger en strangerder.
