Didn't use faucets for a moment now but I noticed this too, sometimes bitcoinker doesn't pay for your referral but in other times it did dunno what is the problem but I didn't consider it as a scam.
Try to contact them to understand what is the problem...
Bitcoinker has a severe rules and it bans addresses easily, you can claim but you will not see your earning in faucetbox.
I tried to contact them several times and never got a answer.
it works perfectly for me and for my referals I know...
but I get no referral commission...
I use space on my sites to refer the bitcoinker link and I see no commission...for me it is scam or have you another worth for this?
