have a tiny quiz before they are allowed to get make any posts.
let them get an account, but before they post, they have to know the rules, which will be tested in a tiny quiz.
also perhaps have a 10 post probahtion period, were if for any reason within the 10 post limit, if they make the slightest itty bitty newb mistake, then BAN. and if they want another account they have to wait 7dys or something.
this is my take on it, i personally dont appreciate newb posts, i sometimes make some, as do others, but extremely newb posts are outrageous.
also those crappy case mod posts ie; duct tape box, all metal box, gets tiring
