Twitter doesn't allow posting freebitcoin referral links, due to considering it a malware (lol). And when using an URL shortener third party service, the destination stops being reachable after some seconds or minutes, so the link redirects to the shortener official page instead. Is there any other way to share referral links at twitter? At least to fix it at user's profile description.
How do you say Twitter considers the Freebitco.in referral link to be malware? hehe. What shortener link are you using? Because I just tried this one now and it works, well I'm still testing it to see if it can be deleted or not after a few hours.
