That's all that needs to be said.
Supercoin dev have confirmed that they are "co"developers. They quickly deleted their response, but luckily i quoted it before that happened. If you need confirmation that he did post this, you will need to ask an admin....
They have deleted all my posts showing the following screenshot and the questions along with it.

You should definitely watch out for Mammothcoin and Supercoin dev. Shady is the cleanest word I can think of.
