Hi.
Pausefisk, I think you are overreacting when you say "involved with such people" and "is 21.com just a scam"? Really, it's beyond their control.
Each MGA-licensed (as well as UKGC) operator will take appropriate action once they're made aware of affiliates who don't play by the rules.
The biggest and more serious affiliates are big because they treat their business right. However, as in any other market where there is money - there are bad apples.
These bad apples shy nothing when it comes to making a quick buck, including SMS-spam. The casinos don't give their partners personal details of players. In most cases, this personal info is collected somewhere, and then put in a list.
That's the reality of today; money and data talks. If you're an active player, who's got a lot of registered accounts due to signing up via third party sites here and there throughout the years, you are more likely to experience spam.
A prime example being leaving your e-mail address to sign up to a newsletter in exchange for free spins (example) on a non-operator website. That's enough for a crook to look up the name associated with your e-mail (not saying you did). With all the public records avail. in Norway, it doesn't take them long to find a phone number associated with your name.
The aforementioned list is curated, and then sold / traded between other bad apples. If one bad apple buys an affiliate website from another, one of the new owners perquisites are the details of the players that signed up with the past owner.
This activity is illegal, and in no way encouraged or condoned by any serious operator, including their partner programs.
Collection of personal details could also be the results of social engineering, or phising. SMS spam is also completely random at times, simply due to demographics, and much more difficult to attribute an origin. The best way to combat e-mail spammers however is to sign up with 1 unique email pr. operator. If - and once - you get the spam, you know something fishy is going on either via the affiliate, or the operator itself.
You not being able to send an e-mail to their address could be due to an outage on your end, or theirs. A MGA-listed company with employees isn't automatically a scam, same as DNB in Norway is not a scam despite having problems with "Evry", experiencing outages in the past.
I've hunted these bad apples for 12 years. Thanks to GDPR, a lot of shady affiliates have been slammed hard. Some even never got back up again, because they took a serious beating. Unfortunately, most of these are small time crooks, that's looking for a quick buck - and small time crooks are persistent fucks.
Let us know how it goes, and have yourself a great day.
