The problem here is, that's the exact same side of the coin. It's the cause and effect instead of two separate matters. Speaking in general, the provider sent their flag to casinos about arbing or other violation the providers detect, and the casinos act accordingly to this flag. The casino does not need two bet slips to compare stakes of the opposite outcome of the same events, the provider did this.
All bets were submitted to the providers. They have all the bet slips and the history. And as established, arbing has telltale. Overtime, these telltale became more and more prominent that the provider will notice. Also has been established, both casinos and provider has their own detection algorithms. Sooner or later, the provider will catch up, and after that, it's only matter of time for them to catch the arbing by matching the history of repeated strange numbers across casinos, then a flag raised.
Not to mention that it is not too far fetched to think that it is possible that those providers communicate with each others in terms of crosschecking violators. Everyone hates violators. And enemy of my enemy is my friend, so, is it impossible to think Betby say, "hi Pinnacle, I'm sending you user with this details, can you share me his betslips from date x to y? I'll return with the result."?
And once that flag raised, it follows you everywhere. You can buy time by using different device or email or wallet, but their detection is [as I've witnessed myself] very complex, they'll catch up with you, eventually.

Hahaha, you have absolutely no idea how sportsbetting works obviously. Pinnacle is an ARB-FRIENDLY bookmaker so they are never ever gonna share user details. They trust their lines enough that anyone is welcome to bet on it without ever getting limited or banned. So surely they are not gonna leak personal data of users to third parties.
Also, how on earth does Betby know if it was Pinnacle that was used as the 2nd book for the arb? It could just as easily have been an asian book, or an exchange, are they really gonna contact them all?
And next to that, most asians and exchanges (and Pinnacle too) are also accessible via betting brokers, where it's even impossible to trace down a bet to a name of the person placing this bet.
Absolutely bullshit what you are suggesting here.
It is very simple: Betby can spot value betting, not arbing.
You... do aware that the mention of Pinnacle here is a figure of speech and simply for [simple] illustrative purpose and can be replaced by any name of provider, and that the point being proposed here is that providers share data about violators, right? The mention of Betby too, by the way. Not strictly between Betby-Pinnacle, other providers are welcome to be used here.
It's... simple point, really. Not hard to understand. So mentioning and making a ruckus like what you do above just make it looks like you're grasping at straws. An advise: stop.
Because, like it or not, the fact is there: Betby flag the user. Where that data come from? Well, above is my guess. If you have a better guess, feel free to share. The fact remains: the instruction came from Betby, not from XYes, or the other casinos.
Uhh... a better yet advise will be: stop trying to push another narrative. The case is nearing its end, the casino is ready to settle. No need to try another useless maneuver for whatever purpose that is... unless the purpose is to sling mud to me, and if that's the purpose, by all means, continue as you like. Anyway, if it's done right, all will be happy. OP is happy, overseers are happy, the forum is happy, including the local pharmacy near my home as I am buying another strip of ergotamine, they're happy too. Emm... not sure if my wallet is happy.
