We don't want Hubski to turn into an echo chamber.

Easily circumventable, though I don't envy the idiot programming this part just for Hubski. May be the best solution, in part because it wastes the programmer's time for this particular instance of a website, and that's effort you don't want to put in.
Would deter bots and common users alike, though I like the idea. I, for example, would've stayed away from a website that requires money to partake in it. Even if I knew somehow that I'd've enjoyed it here, I wouldn't have had any money to donate back then.
Totally onboard for testing / discussion though.
