OK so this week I nominate @socialbot!
It is in service to @schoolforsdg4, so in essence, it is an extra way to fundraise for the kids!
@schoolforsdg4 is giving slum children in Bangladesh access to an education, and they get some of their funding from Steem. Steem also supports their weekly fruits program to help the kids get some good nutrition, and the @womenempowerment program, which teaches women sewing skills so they can have a business and earn an income.
All of these programs are run by @azizbd.
People can support with upvotes and direct donations to the school of course, but also with socialbot, by using the service to buy upvotes (you can send between 0.1-0.75 Steem for a vote) or by delegating to the bot. Delegators also get a daily payout, so it's a win-win situation!
