RaF cant get you banned. If you read carefuly the email from blizz when they remove your raf you will see its actually not your fault, but your refferes couse he refund his gametime money. I would preffer RaF and suggest this chinesse: Skype: wowcharshop
You get 3 refferals (3 emails send from your accounts to another of yours email account) for 10k gold. Every time you want to use a refferal you just contact Sally and you link your reff in skype chat. First RaF will get removed after 3-5 days, next step is use your second RaF link (dont forget to have plenty for every account, becouse after your account get frozen you cant send RaF, and you will need to pay some extras for unfrozen code). The second RaF 99% never get removed but even if it will you got your third. This system is amazing and cheap. I always purchase 20-30 raffs and keep data for every account. Sry for my bad eng i hope i helped.
