Unless most of them are from those “click farms” that like everything on Facebook but are not real users, so they don’t like or share your post later. Plus they are most of the ones to whom your content is shown, so your real users don’t get to see it and interact with it.

The real mess for Facebook pages are this fake accounts that get to like your page even if you don’t pay for promotion (but specially if you pay for promotion). They kill your stats and prevent your content to be shown to the ones that are interested in it.
