I don't know what site he was working on - but opening more than one site on any typical PTC would result in all of them failing, and you would need to reopen them again - one at a time.
Well I'm 'surfing an ad' on bux.to.. it's counting from 30->0, while it's doing that, I was opening another sites' ad, that one was counting from 30->0 too...
Never had any problems doing that.. some had a CAPTCHA at 15 seconds, but once you knew that, you just checked that site after a few seconds
Yeah, I understand completely now! Thanks for clearing that up.
Somebody above mentioned that they were trying to make money online, and I'm going to agree with Aquarezz - most of the PTC sites out there now are scams. They'll let you do the work, and keep the money! Unfair, right? Check out the link in my signature, though, if you're looking for a way to make money for free.
