Yep, that is an issue. One idea might be to look at the data for each referral source (e.g., how everyone who heard about the survey through Facebook heard about EA, then how everyone who heard about the survey though SlateStarCodex heard about EA, etc.).
I agree, this is something we acknowledge multiple times in the post, and many times throughout the series. The level of rigor it would take to bypass this issue is difficult to reach.
This is also why the section where we see some overlap with Julia’s survey is helpful.
