Pet Peeve - hashtag

Today I posted a photo of a flower in Instagram.  I hashtag it "flower".   I was curious to see all the other hashtag of flower so I looked it up.  Lo and behold I saw a lot of selfies, buildings, dog, girls, etc but not flowers.  Out of 21 photos that I checked, only 1 was an actual flower.  Another was a carrot shaped like a flower over rice.  WTF!  Why would people hashtag flower when their photo does not contained any semblance of a flower???   It defeats the use of hashtag if self absorbed people keeps on doing this just to get more views on their photo.  Idiots.
