freebitcoin is not a fraud. They have already paid a good amt of BTC to their users as a reward for completing the task, they were asked to do at their site. There is no fraud case reported against freebitcoin till now. So I think you can trust them.
Considering you keep trying to use my email address at places (including freebitco.in) .. I wouldn't trust anything this user states, as they have compromised my old account on BCT. Everything that my old account (SixOfFive) has posted since October 6th, 2017, should be considered a scam or lies and distrusted entirely. Don't believe me, check the history of the account ... You can see the change in forums posted to and the methods of english used.
