Op, the post above mine has already pointed you to the gambling board and unlike Bitcointalk, the discussion over there is not too heated up because of the low number of users frequenting there and also because most signature campaign does not make it mandatory for anyone to make a post in the gambling board so only those that genuinely like gambling or sports are going to interact there.
I think you have made a mistake in double posting I've also fall as victims of such before, you can just kindly DM the admin or moderators to help you delete one of the post and send them the link of the post you wanna delete. So that they won't think you are spam posting okay...
This is actually an annoying feature ie not being able to delete your post yourself.
I recently made the same error and could not delete it and despite reporting it to moderators it was not deleted- I just left it for now I might return to report it the second time, but the admin should do something about this deletion of post.
