I don't understand if you do not speak english as your first language, being serious, as that grammar should make sense to most. If you do not then I understand you may need clarification.
They being the people I worked with in the jam. Giving credit is widely known as the exchange in a free project for the "lease" of copyright. If where you are that is not the case, I admit I'm more used to talking about things to people who understand that. Once credit has been removed I remove my work. No one's hard work should be taken for free and it's a rule in most jams and websites.

And yes, this is resolved. I appreciate hechelion 's points, so I figured it was good to leave up, if I find out it's better to remove by a mod I will do so.
This is my last response on this as all I wanted was information and have other things to do. I hope it helped clarify
