I don't think this is a necessity. I strongly believe that for any community to be successfull you always have to put user experience first and not being able to post for a few weeks is really not a good first impression. It's basically saying "Thanks for joining the community, but we don't really want you anyway". I think the way we report spam by flagging submissions as spam is how it is meant to be, sure you do get the occasional spam but they never last long because people flag them. This also makes sure the community "watches" over the content and is more user friendly than just pissing off newcomers. I think a lot of people are lurkers and at one point they really want to submit something and it's at that moment that they create an account (you don't really need an account to lurk do you?) so if this rule would be applied it would really suck for those long time lurkers but new account guys.
