Yeah but what happens if they are a shit poster and get banned, I belong to a private site where if your referral gets banned you get banned as well.
Not to mention that there are many ways to cheat the system on that as well making a bunch of accounts and just making a few posts then sending the NSP to the main account.
It can be hard to get NSP but it is worth it in the long run.

Easy fix.

You get NSP for every referral that upgrades to bronze.

Then you either need to spend time making posts, or spend a lot of money to get NSP from fake referrals.
