Barely anyone is taking the misc promotion offer. Get creative with your Plankton marketing and I will reward you

Although someone else would have to set it up, if you want to get into promoting, I suggest something like setting up a donation fund for whale charities ... Save the Whales is a logical choice.
You can set up a straight donation, or set it up to adopt a whale one at a time (think it's like $25/whale).
Or instead of this food giveaway thingy (literal food), use that for whale related donations... whale t-shirts, whale totebags, etc are on that savethewhales site too. Or instead of food, give away copies of that Blackfish movie.
I'd guess you'd get more promo mileage for a good cause, than giving away food.
You're not far off from where this is heading.
So here is some insight. I'm building a crypto trading discussion hub (where you can mingle with key traders and use FOOD to access special areas etc). Depending on funding there will be stacks of real food and drink to be won (i need to work out how to simplify this). A dream would be to get sponsorship for our elite whales (but that is only a dream). Charity is going to be a huge factor for me. I'll have pricing milestones that we need to reach and at each milestone i donate ~$1000 (subject to finances) to a charity which helps feed those in need.
