Re: Can anyone explain to me what is faucet farming exactly?
I have read some posts here regarding faucet farming in gambling sites and I don't have a clear idea what it exactly means. I would like to know because I do not want to do faucet farming without my knowledge and bring myself a bad name. Hope you can clear my query. Thanks in advance! 
Faucet Farming has been explained time and time again, I'm sure a quick search would yield low-bearing fruit. (Is that the right idiom?)
Anyways, it takes multiple forms and you can do it in many different ways as I'm sure you've gathered by now! I've seen folks use VPNs and such to go to faucet sites and view ads, play games or whatever else the faucet site asks of you (or allows you to do). Pro-Tip: Viewing ads and viewing sites will probably result in adware or something else malicious grabbing hold of your computer, so consider yourself warned.
Another thing, I have never heard from someone that they were thankful for the time they've spent farming faucets.
tl;dr Not worth the time, risk(s) or lack of reward. IMO
