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?
