It's kind of a bug, but kind of not. Take for example that you're searching the members and you open/preview a profile. That counts as 1 view. Then you open the profile fully - that's a 2nd view.
Some smartphones, for some reason I cannot figure out, "load" the page 3 times every time you open it. So 3 views are registered for each time you open a profile.
Many people have written to me complaining that this makes them look like stalkers.
