We wish we can explain this, my friend. IMO, popularity in the fandom doesn’t always mean having the most number of posts in a dirty confessions blog. Take for instance – Connor. He’s not that popular in the general AC fandom – not as popular as, say, Ezio anyway, but look at the difference of confessions between the two. That’s more than a 200 difference, which is quite significant.
Frankly, I think it would depend on which area of the fandom you are referring to. The Tumblr AC fandom is pretty much living in its own bubble, isn’t it? So, perhaps the characters that are well-loved in this little world that we’ve made for ourselves would be most likely to get the most confessions here. 😀
