It's raising a lot of flags by looking at the Reddit profile. It's only 17 days old, and he or she is spamming the same link in mass subreddit. I'm surprised it hasn't been banned for self promotion yet.
It looks like the domain was registered about a year ago via GoDaddy, so whoever owns the domain should be easy to locate if it is a scam. Unfortunately it's hard to prosecute overseas where scamming English speakers is big business.
RE: Free Bitcoin! Anyone know if this is real or scam?
