Regarding personal information, I have no problem providing payment information, as long as that isn't tied to accounts/searches/etc. (A separate service, similar to Patreon, seems ideal.) But I do realize that the number of people willing to pay you may not justify the work needed to set something up.

I do understand your concern about not wanting to appear to take donations, though. I just wish I had some way to pay you for your service that doesn't involve viewing or clicking on ads.
