As far as I can tell this just links through to the actual job postings, which may or may not be compliant.
It will be an interesting transition period. I remember job ads telling Colorado residents they need not apply, but if you emailed them I bet it would have been fine.

Since aggregators aren't "job postings", I am guessing at least for WA, the website is compliant, but if you click through to the job postings, then the salary range is not published there either [0]. Should an aggregator be allowed to publish illegal job postings?

Should residents of states where the linked job posting is non-conformant assume that the job posting is not targeted at them, otherwise the job poster would have complied?
After all, the job listing said nothing about Washington state.
Dunno about that. I am currently employed in a remote role at a huge company. I can move anywhere I want in the USA, except Colorado.
