Technically speaking, I would agree with you, but I cannot vote with you even though I’d like to. Of course many people voted that measures should be taken. I also believe that measures should be taken to keep people from letting their dogs eliminate in my yard. I would like to see measures taken to keep people that seem shady from getting on a bus with me.
The things that I suggested can’t be done even though many people would vote with me on similar ones. There is already a city ordinance about dogs in my area, but the cops aren’t following every dog owner around. We can’t just tell people they aren’t allowed on the bus because they wear clothes that are trendy in certain cultures or because they like wearing dark hoodies and sunglasses.
This is the other flaw in your plan. Some people really DO look so fabulous in their pictures that they could be models. Most of us don’t, but you can’t get rid of the few just to fix the rest.
You can’t actually tell for sure that a blonde woman who looks Scandinavian wasn’t born in India. You can’t tell for sure that a beautiful woman wearing a religious head covering isn’t living in the USA. (Many are, in fact.)
You can’t tell a darn thing from a username. One of my friends started out as a team on Fiverr with her husband and they named their account something like johnplusone (name changed slightly) but he later quit. My friend had over a thousand reviews and continues to use her real photo which shows her as very attractive. Her name may not be John, but it’s her and she’s still successful on Fiverr.
So if we can’t tell for sure, how would Fiverr? They can’t. Most of us can rely on gut instinct. If I see a photo of a busty lady with heavy makeup and there are other clues, I probably won’t buy from that seller. Do those photos bring the whole site down? Maybe. If so, the level system and other measures being put in might drive those sellers away over time. No matter what, it’s very difficult to do what is often calling “profiling” people without running into a wall. Your idea is sound and I get it. I still don’t think it would work on a large scale.
