Ok, case at Tropica still open...
But i got an answer from Mrs. Sloto (SLOTS CAPITAL), she assured me that the account of my Mom is not a problem when she will send all requested verification documents before the cashout (as usual). So Slots Capital is not that picky when it comes to playing on the same computer, when it's clear that is not the same person. I'm very happy to hear that, it looks like another proof that an independent Rival is better off...
In other words, it IS the problem as far as the Rival algorithm is concerned. The problem goes away once your Mum sends in documents, and proves she actually exists. Until your Mum does this, both your accounts are linked, and regarded with the suspicion that this is one person with two accounts.
Now, what if this was not your mum, but some complete stranger, and at some time you had both unwittingly played from the same PC, maybe an internet cafe when on your travels, or even from a laptop via a public WiFi hotspot. You would both be restricted by this algorithm until you had both sent in documentation. Whilst YOU could send it in, how on earth (if you are innocent) could you get the other player to send in theirs to fix a problem with YOUR account.
This has come to light elsewhere, with one player disputing a confiscation being told that if he could get the other players who are linked to him to send in documents to prove they are genuine, he would be paid. Clearly, the ONLY way he could do this is if he is guilty as charged, and controlling all these accounts himself. He would just have to get hold of fake documents. An innocent player would have no chance, mainly because the casino would not give him any contact details for these other players, yet this player was expected to get them to send in their documents in order to get paid. Some of the other players had no money at stake, and had stopped playing, so even if they were contacted by the casino, they would have nothing to gain by complying, and would probably ignore the request as a needless sending of their documents over the internet that is of no benefit to them.
This may also be the problem with the Rival database. These links get created quite innocently. The players can't be told how they created the link, and the only way to have the link dropped by the algorithm is for all players in the chain to send in documents to prove who they are. Unless they withdraw, this may never happen, and an innocent player has to live with a link and cloud of suspicion unless they can persuade the operator to override the central database.
It seems the Rival database can fill up with spurious bad data on innocent players, yet there is no way to appeal bad data and have it investigated and removed at central Rival level. The best that can be done is to get the data overridden by individual operators.
This has seen so many honest players tangled up in a web of suspicion by the Rival database that the reputation of Rival as a whole as plummeted. It didn't help when it emerged that most operators didn't know what they were doing, being just "super affiliates" running a website with an individually branded Rival skin, which lead back to one monster of an operator, Silverstone/Bonne Chance, that ran the actual casino side, along with deposits and payments. It meant that players who had 10 accounts with what they thought were 10 different operators of Rival software, had actually opened 10 accounts at ONE Rival casino via 10 different affiliates. Players would never be allowed to get away with joining All Slots 10 times through 10 different affiliates, and running 10 accounts, but it is clear that this is what they would be doing. With Rival, honest players thought it was OK to join 10 different casinos running Rival software just as joining 10 separate Microgaming or RTG casinos is acceptable. They are thus shocked when Rival starts accusing them of "abuse", restricting their offers, etc, purely because of these 10 accounts with 10 separate Rival operators.
Given that this is the design philosophy behind their central database, it is no surprise that the problem exists even with a truly independent Rival casino that uses the feed from the database to grade players into "classes".
Either Rival should clean up the duff data, or independent operators should use only non Rival databases for risk assessment, such as processor run fraud and chargeback databases. Anything coming from the Rival database should not be acted upon automatically, but reviewed by management to determine whether they should apply the recommended restriction to the flagged account.
