Youtube video views?

Question

My view count on youtube is messed up, i logged on this morning and it said i've viewed 7,000 something videos, than I logged in this evening and it said I've viewed over 8,000 videos, which is utterly impossible. I also noticed when I'm searching videos it'll say "previously viewed" on a lot of videos I've never seen before.

Is this just a glitch? Or, could somebody be using my account?

Answer 1

Personally, it sounds like a glitch, but if you want to be sure, change your password.
