I think the Kahnawake reply is bullshit - very disappointing. The algorithm does not form part of the terms, so should not be an excuse to deny bonus points already awarded prior to the ban, which is how their system works. They are also guilty of misleading marketing if they continue to send personal invites related to deposits when they have no intention of giving them.
To use the terms excuse, they should be able to specify the exact violation, and the exact remedial action the player needs to take.
They are also eCogra sealholders, so a second complaint can be made.
This is why they are "proceed with caution". Unless you are VIP and make significant deposits, they WILL give you second class treatment.
They also have this locking of the rewards account when you simply win overall, yet this is not specified in the terms, and has nothing to do with "bonus abuse".
This "deposit an unspecified amount to have your rewards unlocked" is bullshit designed to claw back some of what they have paid out. Many players have deposited considerable sums, but never had their rewards unlocked, and when having asked, are just told to keep depositing and be patient.
NOT depositing actually seems to work better, as a couple of months of you playing elsewhere seems to result in the rewards being quietly unlocked.
So, don't deposit a cent for a few months, and then attempt to redeem the points. Every time you uninstall their casinos, use the "why are you leaving" form to tell them why they have lost you.
They changed their tune with me after they found out how much of a high roller they had missed out on by being too quick to lock my rewards account after a single lucky run on my second deposit. It resulted in them begging ME to "unlock my Neteller account and start allowing them to redeem deposits again"
