It's pretty common indeed but you need to keep doing your part in terms of reading the terms and condition to make sure you'll be able to maximize the uses of the gambling site you pick to play your game, with proper understanding of the requirements you will not be surprise if something is needed to implement since you do your part reading and understanding what is being said.
Accepting the requirements means that you are willing to follow whatever the house is implementing, for you to be able to transfer your money or for you to manage to take advantages of any offers that the house is offering.
This has been talked about a lot before, and indeed the main reason many have problems is that people are lazy to read it or they think the rules in every casino are the same, even though things are very different.
Indeed, reviews can be faked, but we can sort that out and see how many give positive reviews and how many give negative reviews. It can be a reference for us, although in the end we have to check it first. However, for reputable casinos, especially those on this forum, it can be recommended.
Though reviews can also be faked in this forum, you can easily determine that the person who is faking a review is lying based on the rank since most fake review posters create new accounts only for that purpose, if a platform hires some members from the forum that has higher ranks only to post fake reviews then that's a different ball game altogether.
I don't understand why people find it difficult to read terms and conditions when they are putting their money on the line. If I was to put my money on something, I would obviously make sure that everything is okay with it otherwise I won't risk my money.
