Recently Yuri has been voted last liked in SNSD, it use to be Hyoyeon. Why the change?

This was most recently within the past mwaka I believe. Like Oh Youtube everyone is typing her name in and giving her huge heshima now, Then on one of the groups here she came in last too. I mean I don't have a problem with Hyoyeon I just want to know what happened? What changed?

because everybody is not choosing, maybe most of the voters used to like hyo than yul
