Stop using "solve media", it sucks. Use reCAPTCHA instead. Just a view from a site user.
They use it because the owner/admin is paid for the advertising.
Yeah, and the worst part about this is that from some quick searches, it looks like the faucets only get around $0.30-0.35 per 1000 solved captchas. They are basically bothering their users for less than pennies.
I will say that I like the image solving ones more than the "try to decipher this unintelligible text" ones though.
