Hi Piatu,
I will be happy to comment on this from my point of view.
It looks like you joined here early this year. NDN has been around for nearly five years now and I have changed the way I do things around here for many different reasons.
For the first 3-4 years of NDN's existence, I refused to list any "rogue" offers and I deleted everything that I did not personally approve of.
While that is still my preferred way to do things, this lead to a variety of problems. People continued to post "rogue" offers daily and they would get offended when I deleted their posts on a regular basis. It then became a hassle to delete these posts and contact each person to explain why their posts were deleted (so they wouldn't be offended).
So the best thing I could think of was to let everyone post whatever they liked and then use the "color" system to warn everyone about where they shouldn't play.
It seems to be working for the most part.
I greatly appreciate that you make an effort to only post the offers that are actual "no deposit" offers and that are from trusted casinos.
It would be great if everyone could do that, but not everyone is familiar with every casino and it's often times hard for them to make the judgment on whether or not they should post the offers.
So unless we can think of a better system, I think we're doing ok with the one we're using.
It's not perfect, but after trying many different things, it seems to be fair to all involved.
Thanks,
NDN
