That's nice in theory but we need to be honest here: how much people do fully read all the terms and conditions on any site? I never do it and whenever I have a question about something, I always go in livechat and just ask it. Seems the easiest and the fastest way to gather more information but sometimes it is not always 100% accurate. Some support agents are better than other ones...
Yeah read the whole TOS is time consuming, but at least you read the part which you've a concern with it. Let's say you have a privacy concern and you don't want to play on KYC casino, you can type "KYC/personal/verification" in the TOS page... so you'll know does the KYC is mandatory or not. Read the specific rules about the games/provider you wanted to play is important too.
I'm rarely using livechat, most cases they just directly replied with their TOS link or answer like a bot lol.
