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?
Gambling sites can change any of their rules with their official team but after the change they must inform all users through email or site notification to make everyone aware of the new rules. But gambling sites will be held responsible if they hide it after changing their rules and users face problems unknowingly. And for these activities their reputation will be damaged and they will lose many gamblers. and I don't think any reputable casino site would do such a thing.
