I know @vysmek, that's what kept me from using any faucets too, but I mean, the only thing you give them is an email address, and it's only for earning, not for buying. It's a small amount of coin which clicks in every second which in the long term could stack up for some nice value.

But to be safe:
Use another email than you're primary
Use a different password than you normally do
Add adblock and ghostery extension for chrome, which is also super nice for everyday uses
you should be fine :D
Feel free to ask anything buddy
