Do not make topics or replies just to share your referral link. Whether it's in your sig, avatar, personal message, profile, within the post itself, or tattooed on your forehead is irrelevant.

You are allowed to put your refferal link on your signature
So, when you make promotion, ask users to join through refferal link on your signature
And you might want to use link shortener, so every user can't know the refferal link
Any you should know it already when you join this forum
Still referral spam.
If you pay people to register under your ref link it works on games and rounds, also sometimes when people find new promos or giveaways they give their ref link and a non ref link, seems to be allowed aswell.
Still referral spam.
as long as its not actually in the post and the intent of the post isnt to get people to click your reflink (ie, putting the reflink in your sig / pm / profile and posting 'hey go to xx and click my reflink,') having it in your sig or pm is fine afaik. most users in a gambling service sig campaign usually have reflinks in their sig anyways.
