Do yourself a favor and try not to waste much time though, as it is just another form of dust collecting. To much time/effort for low payments. You may also want to try www.captchacoin.com as they pay 200ubtc per 20 correct captchas, which is less time consuming than most places with a higher payout. Be weary, as the captchas are very case sensative. V's are hard to distinguish between v's.
