Wouldn't it be the same as what the tax authorities expect of street buskers, where something was done publicly (just here on the internet) and as a result randoms gave you money/cash (here again the digital equivalent) after the fact with no strings attached?
Yes, just the auditor looked like she was ready to call in the police for fraud when I said it.
Also, I live in a place where that was probably many months pay to the auditor.
