Changing of terms and conditions without notifying the users or gamblers is normal with online gambling websites? Then when you did something wrong or about to withdraw your money they will tell you that you don't read their terms and conditions, and you start arguing with them until you decide to read the ToS again and you find out that it's different.
Some gambling websites consist of wicked owners that willingly plan to defraud their users using the ToS against them, or is this normal? Have such happened to anyone on this forum before?
If it is stated that devs has the power to do so in the first place, then that's just fine. Problem here is gamblers or users of a platform not even reading the ToS but I bet most of us do, not only in gambling platform but to almost evrything that has it. We tend to just click agree. But on my end, I have no big expectations if I instantly agreed a ToS such that if anything bad happen in contrast with what I have agreed, I will just move to other platform. But ofcourse it won't be the same to all things ofcourse especially it money is involved.
it will make the case become more hard for the players since the casino already stated that and whatever their wish to, they will change the T&c to suit and favour themselves.
But I have not seen any casino that does that yet and including it in the terms of service will discourage potential players from using such casino.
As stated above, they can not do this. They can't simply change their terms of service overnight to win a dispute against one or some of their customers. A scam casino may do it but a reputable one will never do it. Besides, as I said above, even if they introduce some changes to their ToS, the changes aren't supposed to have a retro-active effect. So, it's not going to change anything.
ToS indeed should be something which is absolute but as I have said above, there are policies open for amendment which are sometimes mentioned in ToS, and that is to make changes with perhaps fees, if it is needed. Most of the time, this could be seen with unregistered gambling sites and with licensed ones, policies are fixed. Also, not all changes are subject for fraudalent behavior, some are for the platform itself.
