Google is telling search that some of my posts are 7 years old!!! Wth?

Since my traffic is so dysmal, I've often wondered if they blacklisted me. But I guess this works, too, if they want to bury me. No one wants to see a post this old, even if it's a cartoon.

I know there are plugins to update the date. I guess I could go in and just update everything, with no penalty.

But why are they doing this? Do they really think they're helping anyone? LOTS of people dont have a date in the url!!

Oh, no images allowed here? Search clearly points out that post (cartoon) is 7 years ago. :(
