I just noticed this myself with another post. Surprised there isn't a definitive answer on this.

Now that I am more experienced, I know the reasons of this:

People (and bots) voting without even opening the posts at all, just for the reward, etc.

Also, you could open the post in a different platform, like Busy, and as far as I know, the views counter does not change on Steemit.

Friendly backup - may be. No reading only likes. Part of some alliance work.

Indeed.....a gud question
