It's specifically against the guidelines to keep registering new accounts, and this is a good reason why. We have to have ways of determining credibility and authenticity, now more than ever, and a track record of good posting is one of the best ways to do that. We are drowning with spam and low-quality posts/projects posted from brand new accounts. If it's a well-researched, high-quality post, of course we want to give it exposure. We just have to be realistic about what we're up against.
