"It takes only several purchased upvotes to build reputation to over 40. So this solution wouldn't really help much."

But it's ok if a newbie get some upvotes and have over 40. I would a newbie without upvotes let write what he want.

If he spam and people downvote him he fall under 25 and than he should be limited.

First to think, that this newbie come here to participate and not to think, that he come here to spam - this is the change in mind we need.
