This is a valid point, I tend to agree pretty much with that, but our personal opinions on the matter are not important at this point. You just have to remember that this BtB team didn't invent their own rules. They (we) just reminded the players of the long-established rules from years and years ago. The rules that are constantly being exploited and abused more and more with every BtB, so that's probably the only reason for them being expressed in the way which sounds more "loud" than usual. And a very important point - "abuse" DOESN'T mean not finishing the level, it just means never even intending to.
Based on my experiences in the last four BtB events and as a member of the current BtB team, I guarantee that everybody who shows the slightest honest intention of building a level in any way( level pictures, sub-forum discussion etc.) won't be considered to have done anything wrong, at least in my book.
I'm not saying all of this for the purposes of "defending" Michael, Jesus, myself or the team in general. I am saying that because I would just love to see more levels being released. And trust me - The difference between honest registration and the "fake" one is always obvious in the sub-forum during the building period, so I assure you there is no way for anyone "innocent" to get labeled in any way, regardless of him/her finishing the level or not.
Not having builders such as Mytly and yourself only because of the tone in which some posts have been written, I would personally look at as a very big defeat of the almost always friendly community.
