Hi there

I was wondering if there is a policy regarding posting referral links for online competitions? i.e. Using a personalised link to an online competition which gives the original poster extra entries in the competition every time someone uses it. There would also be a generic link to the same competition. Often used with Facebook or IHeartradio competitions.

Should the post include a disclosure that this is a referral link and also provide the generic one, only provide the generic link or no need to specify either?
