I am in CO and saw one ad that had a link to a special page on their website to "comply" with this regulation. It was a blanket statement that salary can be between $20k (can't remember the low end but it was something like that) and $1MM based on position and experience. I was very put off by that and did not apply. I didn't take the time to look into the legality of using a blanket statement like that but it seems sketchy to me.

The legality is "not so much" but for smaller companies they can get away with it (because small companies are unlikely to have defined titles and bands to begin with).
