Bot will respond to OOO person, telling them they're OOO

👋

I noticed that if someone who is OOO @-mentions themselves, the bot will still pick it up and let them know resulting in a message:

👋 Hey @JasonEtco...

Letting you know, @JasonEtco is currently OOO until Saturday, March 24th 2018. ❤️

This is obviously a pretty specific edge-case, but it'd be ✨ if there was a check for the comment author === the OOO person.
