Nursery for New Members

If I were a spammer it wouldn't really be that hard to program a spam bot to register, wait 24 hours, quickly post 3 pointless posts, then spam the forum silly before those 3 pointless posts were reported and that would be that. Damage done, didn't change anything except forcing my bot to delay 24 hours.

Making a filter that annoys regular, decent people without blocking the spammers is a fail in my book.

Clever, except that your 24 hours don't start until you've started posting. The Nursery system works very well indeed and we get hardly any spam. Win, not fail.
