I think gone are the days of automatically being able to tell "plants"/amateurs based only on the wristbands. I think there has been an increasing amount of "plants" with wristbands on the right wrist for the last few parties now. Although, all amateurs seem to have the wristband on the right still. As far as this party goes, I think of the three girls that fucked, only the first is possibly an amateur. And I think the girl in orange is also a "plant". I think that part 1 showed that this party had some promise, but part 2 disappointed for me.
We've said it before but plants are obvious due to tatts, immediate willingness to suck every available cock and they acknowledge the camera filmng them. Amateurs carry a purse or handbag, don't give BJ's or fuck unless they are in the corner and away from the main stage or crowd. Of course there are exceptions to these rules.
