I believe Siri is a microcosm of the Miss Freeones category. For the most part it is being dominated by porn actresses that may or may not even know the forum exists.
The question is why. Probably because the big production companies want "their girls" to do well and win a title to help advertise their movies.
So they are probably having all their employees vote. Maybe even hire computer programmers to stuff the ballot box for them.
All of this is purely my opinion and I may just be a :tinhat:
