There are a couple of IFs a developer can implement to avoid havoc. IF 1st post + IF membership not older than 2 days + IF 3 reports of spam = hide post from viewing. The reason I'm saying 2 days old for membership is because of time zones. The spammer could be originating from a different time zone, today is the 7th, but it's already the 8th in Southeast Asia, Indonesia, Australia, etc
