those auction sites are total scammers. there was a guy who used to sell software so you could run one yourself...complete with autobidding bots so youd never lose an auction to a real bidder.
They also make it out like you bid pennies, but the bids are increased by one funny money penny(any made up unit would work), but each 'penny' really costs 50 cents to a dollar.
So if they auction a tv for 50.00, they just sold a tv for 2500-5000 dollars, and to win that bid you might have spent 100s to win a bid (or worse, lose and gain nothing). Thats right, you pay for bids, so every click you make you pay for.
Beezid starting adding disclaimers that they are actually a game, and your paying to play ie out click the other 'gamers' to win the 'prize' because the lawsuits fooding in. Ironic as this is a practice they ripped straight from free to play games, who also fleece people out of money. Real cash -->bundle of game 'currency'/gems/point#-->spend tons for reward not worth real cash.
Ive had success online from amazon affiliates and mturk, tho mturk is a lot of work for tiny amounts. I have talked to people online whove done etsy and fiverr with beer money level of success.
