First of all, you don't need to compare other platforms with BC.game. Every platform has a different set of rules and you need to abide by them. As you mentioned that you mistakenly selected "document," it seems that you tried it several times, which is why you received a message stating that all of your attempts have been used.
Try to contact the support and tell them the situation, maybe they will help you. By the way, how much did you deposit on that bonus offer at BC.game?
It is absolutely normal for anyone to compare casinos because this is how casinos can be compelled to be up and doing if they must provide better services than their competitors to help them win customers overs..
And when it comes to every casinos having their own set of rules, there are rules that are completely unjust, and to make the casino realize that their rule is unjust, users must compare such rules to that of other casinos with better rules, so the user isn't wrong comparing other casinos to bc.game, if I was in his shoes, I would have done the same.
BC.Game should look into his issue and ensure it's resolved, what they are trying to do is stealing, it is robbery to block a user access to his money as a result of not being able to pass at first, and completely seize them the opportunity to try again.
