Now I'm investigating.

Lots of my older posts have negative numbers. A person just liked an older post of mine and I went to it and it has -57 notes. Very odd. It looks as though the notes simply 'turned' negative. I'm quite curious, but, of course, would never learn anything from Tumblr. In fact, you guys should ASK ME THINGS and I will answer them like a member of the Tumblr staff would. C'mon, it'll be fun.
