Hi Lyn,
Unfortunately, Steemians can only donate so much directly to a post by upvoting, they only have one 'upvote' to give, and even then, the amount they can give is limited to how much Steem Power they have.
However, yes, they can always donate Steem Dollars directly to you manually (using Steemit wallet SBD transfer function), or via a button like the one I put in above.
Lyn, you may like to set up your own donation button by going to steempay.io if that would make you feel more comfortable. Perhaps you could put it in this post (and your next post).
Otherwise, yes, of course, they could always donate directly via freeross.org. I see you have a Bitcoin address to donate to, might be an idea to also add an Ethereum address they could donate to? Have someone trusted (or yourself), setup an Ethereum wallet as well. Do not use an exchange.
If you would like to talk further regarding other avenues, you have my email. I would be honored to help.
I was thinking a 'FreeRoss' token based crowdfunding campaign might stir up the hornets nest.
In any case, whatever you do, please know that you have my support (and I think everybody else's here), and a geek at your side to help you with anything you may need in relation to such matters.
Kind regards,
Optimistic
