I still have mixed feelings about it, it's at least very naive not to keep accurate records.
In hindsight, with the ~2 BTC - yes.
However it didn't start like that. I didn't donate to this specific effort but I've given money in similar circumstances. Let's say you give $100 to someone halfway across the world and the person provided e.g. a picture of a happy crowd with what could be $100 worth of groceries in front of them, is a receipt going to change anything? Without being there in person you have no way to verify it so comes down to trusting - or not - that person with the $100. And if you didn't ask for a receipt to begin with, you'd be an asshole to start asking for it a year later.
Anyway, with the somewhat spotty evidence provided I have no reason to believe that crwth is at fault here. There seem to be significant amounts gone to the other two guys, so there is probably more work needed to untangle that part.
