Hey man, that's fine. But the people that say "no" only guarantee they'll never bring the right idea to the table.
Where I'm from an internet connect and a computer can be accessed for free...the State pays for it. So if the homeless in my town knew about this opportunity, could write, could figure out how to get a bitcoin wallet (and how to convert it to cash) they could use the free computer and internet and post for an hour every day and earn some money to get themselves off the street.
Now, they gotta be genuine with their posts and such but still the opportunity exists if they just knew how to do it.
Well your definition of what rich is would be different from most people's point of view. A dollar a day definitely can help poor people but it's no way going to be enough to support people's basic everyday needs. And people would also have to have internet connection for them to be able to do signatures. I mean, it's good that you've brought that up but I think that won't be enough
