There are almost hidden disclaimers on what I perceive as paid advertisements which of course is common in the advertising industry. Not all streamers doing these kinds of reviews might put all of the factual information and instead will leave you wanting for more information. Internet personalities are not all nice guys in my opinion. Some have agendas of their own and they make sure that they hide any sense of falsehoods under their skills in acting.
Many are doing that, they are only after with the potential profits that they and get from their viewers. Not all are nice, but most are wise to lead you to follow them and bring them nice cash in their wallets. It's barely needed to make sure that you fully understand what you'll going to do. Not doing your research will always lead you to risk.
Disclaimer or anything that streamers provide still not an assurance or protections, any participation that you'll going to do are still all on your shoulders. Best to be wise if you are only looking to have some fun.
Play responsibly and forget about those fake bets that you watch. Be more realistic and aim for your desired target.
