No, I don't think so.
Firstly, I want to say that musing is not a airdrop site. Secondly, musing is related with crypto currency but it has no referral system. Finally, it can be say that musing have no referral system .
No it does not have any referral scheme and we do not want also. referral system is worst system in my opinion, I am glad that neither steem nor musing has something like that.
Thank you and Have a great day.
