There was a "Job Spotter" app in the late 2010s where you would take pictures of help wanted signs and get paid small amounts, a weird bridge between online job boards and physical signs. I made $50 in five months, then the pandemic killed it. During our lunch hour, my coworkers and I would race to each storefront to see who could get their submission first.
