How come some people's names are in lighter blue and are bigger?

I went onto today and saw that my name and a lot of other people’s names are lighter and bigger. Can somebody tell me what this mean?

I know I’m gonna get AT LEAST 5 boxes. But I’m not sure if this means something.

probably means that there account is verified

Oh okay. Thanks. I assumed at first it meant loser but then I saw Sakaris name was like that so I figured it was something else.
