Yeah I was thinking of doing the same thing. Thing is, the content has to be really good, because even if it happens to get some momentum and moving to the top page, if it's crap, even more will downvote it. If it even hints as an 'ad', it will get downvoted fast. I have my idea planned for when I'm ready, and I hope it doesn't get spotted as an ad.
Just make sure the account you post it with is old and active. If you've been there for 6+ months and post regularly, they won't suspect a thing. But if you're less than a couple months old and have like 10 posts, you'll get called out.
