For data gathering? Pretty much anything that doesn’t fiddle with the values. Usually, bespoke apps or applications specifically designed for survey data. People actually use spreadsheet programs a lot, but those who do spend a lot of time on ensuring data gets entered correctly.
Fun thing, the last time I used LimeWire was actually in Linux. So obviously I was immediately highly suspicious about .exe results. (Wouldn’t even have been able to run them anyway. Wine was far less functional back then.)
