I think their multi account detection is not flawless. Many of the accused players say they only have this 1 account they are playing with.There have been many complaints in the stake forum, many of them sound genuine and also a little bit desperate
.
If it's true what they say, nobody knows, but I think stake also makes mistakes.
I on the other hand, know several people that have 2-3 accounts at stake, and none of them is being blocked from promotions. Last monthly was normal for them, for all accounts. So obviously they are not detected, or at least not yet.
If their multi account detection is flawless, their casino will be either compromised by cheaters or their reputation will be damaged by mistaken bans against their users.
After years, Stake.com has still maintains its high reputation which says all about their platform, available games, multi account detection tools as well as their trusted operations from provably fair to withdrawal process and customer support.
If you run a casino which has flaws behind the scene, it will be exploited by cheaters and just one or few big wins can destroy your casino budget and if you refuse to proceed withdrawal, break your Terms of Service, your casino reputation will be damaged and nearly impossible to recover.
