When a referral gets placed on hold, please feel free to contact us and we will be glad to provide you with information on the action and whether or not the user can take actions to lift the hold. Sometimes it's a simple issue the referral can correct. Before it happens, if there's a user or users that raise concerns with you, you can also open a ticket on them and we will be glad to check on their account for you.
However, the two others were valid referrals - personal contacts who are relatives that completed offers on their own computers at their own homes with unique IP address on secure wifi, unique billing addresses, who never completed or participated in the offers before...they are ENTIRELY legit referrals.
Referring family is fine (provided their reside and participate from their own home or residence), however, when one person is offering to obtain multiple credits for you on the same site, "relatives" often means the same person participating under multiple accounts which is a violation that results in both accounts, the original and the "relatives" account, to be shut down.
