Green and Grey Dots

Next to some people's stars, sometimes there is an itsy-bitsy grey dot.

Then just today I started to see larger green dots (almost a small circle), one right next to my name!

Am I being marked for punishment 😳 or exemplary behavior 😀?

Can someone clue me in on the meanings of the grey and green dots?

The grey dots mean that the person is a subscribing original pawn star and the green dot is if you have moved in the last 10 minutes. 😛
