My concern is with the phrase:
“in their effort to win a prize of a game or bonus gift…”
Now if in game, you could convince your marks to do this, using no outside app, voice comms, or the like… Maybe. But if you start using external comms, websites, or the like you may have problems. Now granted, it may not be the extraction of skill points that is the problem, but rather the use of the external equipment but it could still be problematic.
I say this because we already know that bonus rooms can lead to a ban. We also know that the old fake wallet API trick was banned. This latter one was banned not because of the scam but because of the burden it put on CCP customer support and the negative image it gave to API transactions.
So again, if all done in game, you may be ok. But I would petition the GMs directly with all details and see if you can get a ruling before you take any action in this regard.
