I’m glad to see people are so concerned with the fairness of this competition! It shows that people are excited and engaged, which means it was a success!
I have no problem with people sharing their games on social media or asking people to vote for them: sharing your work doesn’t work against the spirit of the competition, it is the spirit of the competition.
Regarding the allegations that they are sock puppets, though I cannot fathom why a cheater would have his alternates comment instead of just voting, regardless he has said he would refuse any prize if selected. Surely, this will suffice.
Thank you for your concerns, however. I hope that everyone has fun and enjoys this jam not as a ferocious competition but as a collaborative experience. It is not about winning but about working and growing together.
