Limited PM's for first n posts?

[Prank]

Hi Guys,

We're getting lots of spammers registering and some of them are taking to PM's to spam discreetly.

What I'd like to do is restrict new users for 15 posts or so. Starting with just not being able to PM during this period.

This used to be a setting but now it seems that I need to make possibly a 'New Member' group to put new registrations in, which is restricted, and then auto promote them to the Members group after 15 posts. Is this correct? Is there anything I should know before I do this?

Thanks,

Christian

Yes. 

Or use a third-party solution.

Indeed that would be the only way in which to do this within the core platform
