I would like to propose a solution about these newbies that don't do anything than damaging and spamming the forum. Once a newbie creates a new topic, the moderation team must approve it first. I wouldn't suggest posts generally because there may be some honest newbies that face an issue. Just for their topics.
I've suggested this before and I still don't think it's a bad idea as it will stop the majority of spam bots of malicious users, but this alone wouldn't stop the current eth pill scammers as they've seemingly hacked hundreds of older accounts including many higher ranking ones which are used to spam the malware.
