I agree with this. Posting +40 Posts would be a lot better for a referral. If not, any random LQ poster would invite more LQ members.

The patience needed to post replies/threads that matter being lengthened would filter out the unwise referrals.

EDIT: I take back the forty, I say double up and make it fifty.
I mean, let's be honest, if you make the referrals cheaper, then the gates being closed really don't make a difference anymore.

That's only double the effort tbh, if they want to get in that's not much of a road block. I was thinking more like 100, really makes you think about who you invite, then again 100 may not be that much of a road block either according to what I said earlier, but it's a start? The more valuable the invitation the less likely they are to jeopardize that with poor quality or trolling.
