Yeah, that's exactly what I was describing in the above post that my guess is.
But regarding the other part of your comment, I think you've got it wrong as there is not in question some bot or bots action that would do this classification. Quite in contrary!
The thing is that this classification is done manually by members. Every Steemit member who uses this tool can make his/her own choice upon own impression of other member's account and vote. What makes the whole thing even more awkward.
If only bots (who are always limited) are in question, I probably wouldn't even bother to write this post.
Ah, okay, then.
