Please read everything.

I know this is probably not a bug, but I'm tired of the way they enjoy this bug.
All, if entering a server with offline mode, can use the name of any User and thus the skin too.
In Brazil, this happens a lot, they put "offline mode" and put a password method inside the server.
Since when bought minecraft, I could no longer play on these servers, my account is used in all these servers because they want the skin.

The offline mode should disable the skin of those who use pirated minecraft.

PLEASE do something about it, I want to play in peace in my favorite servers.
