As an interesting alternative, imagine that the site asked you to print out a random number on a piece of paper and (within a 2 hour window, for example) film yourself holding it in front of a building or landmark that you claim is within 100 miles of your home. You could cover your face during the filming, or temporarily affix the paper to some surface, like a tree, and then upload your video clip to a selection of randomly chosen existing members who would cross-reference your location with Google street view, and try to check that the image isn't a deep fake. Of course people would eventually start offering a paid service of carrying out this process on behalf of the bot farmers, but the algorithm could demand that your filming location not be somewhere that a lot of people have already used for their recordings, which would push up the cost of someone trying to create multiple identities locally to them. Also, offering this location spoofing service could be classed as (conspiracy to commit) fraud, and the risks of getting caught by going to a specific location at a specific time as part of a sting operation should be pretty high, and not worth being paid minimum wage for.
