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?
Yes, unfortunately this is one of the dirty tricks that many casinos in this board use in order to profit from players illicitly. I've seen many complaints and accusations claiming that accounts have been locked/flagged with reference to ToS that did not previously exist. Most recently as far as I have seen, is the accusation of Kingrojie against Stake.com. There are many more like this.
It's wrong. It's fraud. A lot of the board are guilty and a lot of this casinos deserve to be boycotted.
That won't happen though.
