The TOS of gambling sites is very necessary to be read and well understood by the bettor that want to make use of the site, the reason is still for the sake of the bettor not to do what we not later favor him, there are many gambling sites if not all that have similar rules but not fully the same, that is why we still need to read the TOS in all the gamblimg site we do visit in order to avoid mistakes.
Exactly. Some user you may see have been blocked by bookies, confiscate their fund etc. The reason is that they don't read the TOS and they've made a mistake so I don't think it's bookies fault for not reading the TOS
