As far as I know these are the legitimate players in the top ten right now:
HappyBooker
Sunny274
Bogle
FortuneTeller
pollo frito
Sammy John
The other 4 are definitely glitches. Even the legitimate top tens might have glitches. My portfolio glitched because I was shorting CFC when it got sold, so it added an extra $24,000 to my portfolio. I got them to audit it over the weekend, so now it's correct, but I imagine that at least a few others have similar small glitches.
