we're supporting a study on the role modders and rom hackers play in games preservation and archiving - if that description fits you and you'd be willing to participate in an interview, fill out the form here: https://forms.gle/ESVw2JzH6SXK95dcA
It is a nice research you are doing and it would be even nicer if it didn't give Google lots of data points on the participants for free.
I suggest you use Libre, gratis, and ethical software to conduct your research! I have refused to participate in researches in the past when I saw they used Google forms, even though this one does not apply to me.
So you may not knowingly be losing some participants, as well as you are comercializing the data of the ones that do participate.
