Thank you for raising the question and checking the site. Let me clarify that this site is running for a while, but there were no Bitcoin integration to it. You can still try out and use this site without bothering about Bitcoin as it is free to join and fundamentally a credit based tweet exchange site. When I thought about payment, I preferred to use Bitcoin rather than traditional FIAT as I am dealing with virtual credit which has a dangerous problem of chargeback. That is when I integrated this Bitcoin earning option as well, because when someone buys credit with Bitcoin, I have no problem in selling them for the same. But, as it is just integrated, neither anyone have spent Bitcoin nor anyone have reached the credit threshold to earn Bitcoin. In the mean time, I urge everyone to join the system and take advantage of twitter to promote message using the system.
It's not a personal trust issue, it's about this being the internet and scammers are everywhere. So until someone else rather than the owner confirms that it's working I will not invest my own time in it! However, as soon as someone confirms it I myself ( and I'm sure a lot of others ) will gladly join and contribute. Also as I didn't mention it before, +1 for the concept of the website, it's really clever.
100% agree, cause I am of those people that is looking for some opportunities or giveaways to earn some bitcoins. As it was titled "Free Bitcoins" it sounds like a gift but turns out not true. Thanks for your comment sir. Hope other noobs like me would try to read the comments firs before going to action
