This is public voting, which means that participants can get their friends to vote too if they want. It doesn't necessarily mean that developers are just creating alt accounts. The mistake with this jam is that I didn't put a requirement to hit a certain amount of ratings before unlocking the $25 prize (we did so in the last jam a gained over 500 ratings) so that's something I'll definitely bring back. But I will say this.
The community voting is simply to engage more of my members who didn't participate in the jam and promote the organization as a whole. We put a small prize of $25 just for fun and to make more people inclined to promote, but this prize pool shouldn't be something to really complain about or be competitive for because I didn't need to add this prize in the first place if I didn't want to. One reason we are doing public voting is simply because we don't have enough members to make developer only voting very effective. There's always going to be the people who say that public voting is "unfair" which is why it doesn't count for the actual prize. This is just supposed to be a period for fun and to give another developer a chance to win. If you haven't already, please also join the discord because communication there is faster
