neon23, I ask same question some time ago, and this is the answer from one of the global mods:
Technically they're against the rules, but people kinda started to get a free pass in the Gambling Discussion sub a while back. Personally, I don't really care about them regarding users like tipsters who are giving their picks away for free and include a ref link if anyone wants to put the bet through them. At least they're putting some effort or at least thought into their posts, but I'm sure many others (including mods) would disagree. If someone just signs up to post a ref link though that would be a different story. Theymos will probably say take them on a case by case basis but I'm sure everyone has a different opinion on in what context they should or shouldn't be allowed (especially regarding tipsters).
From this it can be concluded that Gambling board is to some extent exempt from the rule
"no ref links in post", and it depends of mods/admin whether such a post will be deleted or not. Rules should be the same for all users on all boards, but as we can see there are exceptions.
The way you want to post referral links is probably not allowed, but you can try and see if such post will be reported and link removed.
