Seriously though, I do hate twitter hashtags in general, and especially when people use them outside of twitter...
I understand why they are doing it's just the way it's presented on screen is totally obnoxious.
There's no reason they need to have a giant animated lower third graphic on screen during forecast segments promoting a twitter hashtag.

The graphic is to tall and blocks the intensity chart on the bottom of maps.
Plus they already have the #tornadoweek hashtag in the box on the left side of the LDL.
