That doesn't mean it's welcomed. I'm only telling you. It's up to you if you want to upload more of that stuff, but don't think that it'll be easily approved (at least that's what I want to believe).
A single page should be fine, if you upload the best or funniest part of it, just to let people know it's there. And then they can download and view it.
But as for doujins that are only online, those are fine.
