You've just reminded me, I've been meaning to ask, I had 5 referrals, then it was four, then seven... So, I guess I'm wondering if the referrals stop playing do they disappear and then reappear when they start playing again?
Referrals don't dissapear if they were once active and then stopped playing. They only disappear if they created an account and never made any faucet claims or gambled after a certain period of time. Since they are deleted from the database the only way you can get them back would be if they created a new account using your referral link.
