Hi there, this seems like a bug to me. It also says on the front page that you get 3 USD when signing up- see this image:

You have two options:

1. If you are not sure if this is a bug than post to https://steemit.com/hot/steemit-issues
2. If you are sure that this is a bug than you can post your issue here with screenshots and a description: https://github.com/steemit/steemit.com/issues

Thank you!
