I'm not sure whether this is appropriate for this forum but I thought it might be worth a try, because this seems like an easy and costless opportunity to possibly do some good.
Laura Duffy and others are donating $1100 to Against Malaria Foundation for every round she wins in the Neoliberal Shill bracket Twitter poll. She has raised $3300 already, but is currently behind in the Round of 32.

About the foundation:
Against Malaria Foundation works to prevent the spread of malaria by distributing long-lasting, insecticide-treated mosquito nets to susceptible populations in developing countries. AMF has been active in 36 countries in Africa, Asia and South America, with a particular focus on sub-Saharan Africa.
Laura is posting the receipts of her donations after each round and so are other donors. Here is her receipt from the previous round. If you scroll through her Twitter feed you can find proof of donation from other donors.
I have asked the organizer of the bracket if soliciting votes from people outside the Twitter community was allowed, and he responded in the affirmative.
Only rule really is no vote botting. otherwise, feel free to share the bracket polls to forums or subreddits!
Sorry if this is completely not suitable for this forum!
