I joined Ads4Cash a few days ago, it always sounds good: provide 0.5 cent for each ads click, and it has many ads wait to click. so I join it and want to earn extra money there,but I found when I click the advs, it show me these words: " Thanks for supporting our advertisers! You will receive?.500 cents.(1/2 cent) Once you have visited our advertiser's site for?input type=button ". I don't know its meaning, and what I should do then? if anyone joined this website can help me? thank you very much.
