Thank you, unfortunately it didn't I, an error left me something like invalid parameters

That's strange. Would you mind giving me the full error you are given, as well as what this function returns - var_dump($rewards);

I suspect there is some javascript you can put into the url to bypass validation? Any help?

It probably depends on how your faucet is coded, but no javascript should be able to get around a captcha AFAIK.

I think that I'm going to stop as well, right now I have a lot of traffic.
Thank you very much friend.
