Some of these are clearly typos in the job listing. For instance 125k to 1.75M? I bet they meant 125k-175k... would be good for the site to filter on variance and hide jobs that have very large ranges
There's one on there that's $28.58 - $8,000.00 per hour that's especially hilarious. Assuming 40 hours a week for 52 weeks that's roughly $60k - $16.6 million for a salary range. Obviously bogus.
