that's a very weird rule, at least as long as the quality is good
This is not good quality. Maybe it can be past the wip stages but at least wait until then. Hema has been shilling for patreon for months now. All of his posts deleted. I would advice him to get a paper route instead and draw in his own spare time.
There are other wip posts on Danbooru sure, but these at least have a fair degree of merit to them.
Please, please, PLEASE do read the Community Guidelines before you post stuff that goes against the rules. It'll save us immense time what would otherwise go to weeding out chaff and ban people just to keep the peace and order of the site. We don't like to ban people, but we will do it if there's sufficient reason to do so.
