The dogs working at DOGE haven't the idea on what are they looking at and are lying to cover it. I wouldn't count on them exposing anything but their asses.
I think your best bet is to organize it "secret santa" style in an open format where people won't necessarily suspect that everyone but them is a paid actor.
There must have been studies on this. Putting money into the mix is a bad idea IMO.
Is there a way to remove the author trust factor? I suppose you'd have to pay in crypto to keep it anonymous, and this app would give you a random QR for a strangers wallet. How can you confirm that it's not the authors wallet, or an alt. Seems tricky.
That said, a donor could do the same thing by dropping cash in an area with high pedestrian traffic, and walking away without looking back. That said, those interested in the data collection aspect would be disappointed by that method.
I don't think paying in crypto increases trust for the regular Joe, maybe Alice and Bob will be more likely to join. This would select a very narrow crowd and skew your results massively.
