Heya, my first sift post and sorry it's one of those annoying "why" posts!

I was browsing my VideoSift profile and clicked on the voted down link not expecting to see anything there, lo and behold there's a video I've apparently downvoted. Curious...

I am fairly sure I've watched that video in the distant past but don't think it would be something I'd up vote, and I've only recently acquired the ability to down vote (Mwuhahaha... ahem) and I also noticed my name at the bottom is in default blue instead of bold charter purple - possibly indicative of a down vote being cast at a time before I donated for charter membership? Has anyone else experienced something like this?

Ah well it's no biggy in the grand scheme of things, just a little puzzle to amuse the grey matter for a little while
