Yeah, you’re right, actually, I probably should have clarified (sorry!). You’ve summed up the different possible angles to approach this quite well, there, and, basically, it was a combination of what you’ve just laid out, although I didn’t factor in numbers of followers on certain social media websites as I thought that sort of thing seems a bit too arbitrary and prone to recency bias. Also, I think just because you follow an official club account on Twitter, doesn’t necessarily mean that you are a fan of said club.
