No one will like hearing this answer but they may already underrated the issue of it being bad data and have a good reason not to care.

Here’s the thing. When “none” or “skip” is there, people gravitate toward it. You end up getting 75% of people saying “none” for every question, and then your entire survey is meaningless. I hate surveys too. Everyone hates them. All the more reason to just mash “skip” or “none.” Because fuck you and fuck your survey.

Meanwhile, what % of people don’t touch any of these social networks? Maybe we can’t say for sure, but it’s way less than 75%.

So you’re choosing between two possible sources of bad data, and choosing the one you know to be of lower magnitude.
