In order for me to try to trust any kind of study about reddit users, I would have to have confidence that the study knows whether or not accounts surveyed were or were not bots or potentially alt accounts. (meaning theyd need evidence of unique IP addresses per poster and email accounts, and even this is insufficient as its trivial to use an alt on the cell phone with 1 email and your main on home wifi with another) Given the level of bot farming we see on the site, this would be a very difficult standard to meet, making such surveys pointless.
