Since there are many registered domains of similar names, not every one of those are legit. Many are run by scammers to prey on users who make a common spelling mistake in the domain name and run a clone site used to steal their money. Some domains are just linking to a referral link often run by affiliate marketers.
To be safe, do not visit any such link. Use the one that is official. No need to even confirm whether those domains are real or not.
I obviously did not want to use it, I used it by mistake and caught that I was redirected. I was posting just because I was wondering if I narrowly avoided getting fished, or it is PD's way of redirecting.
@carsonjoey I would recommend you to install a antivirus software which can detect phishing links like these, and try and avoid being redirected to such spammy sites as they can download unnecessary software in your system which can then steal your information without you even realising it. Furthermore if team Primedice is aware of such fraudulent sites then they should immediately send them a DCMA notice, and send the same notice to their hosts because hosts will then have to deindex those spammy sites.

The site isn't necessarily a scam or phishing site. From what I can see, it just redirects to primedice.com with a specific referal code. Seems like someone just wants to make a buck on the fact that pd didn't register all relevant domain names.
