I saw that one earlier today and had a good laugh; they claim to be freerolling from freedoge.co.in when the site stopped free rolls more than a year ago. So taking that into account, I doubt that user is smart enough to leave no trail on this faucet abuse. (no same IP, no refs, not sharing an address, automated to click every hour literally,....)

Offcourse it's not allowed. It's called faucet abuse. Reporting these things is almost pointless, because there is no way to know User ID's of that person. But Freebitco.in fighting with these abusers daily and they ban them sooner or later.
It's also very likely that's just scam attempt and this user selling not working method to abuse faucet.
