You are right, sometimes I questioned a lot what they took into account to make decisions to see what factors they based on to make the review and why they chose those casinos as good when they had a bad reputation within our forum and their answer is that They were based on other factors such as withdrawals, promotions, bonuses, but in the end, if this is not verified, then it is not possible to speak well or badly, I think that is the detail that is lacking.
That is why every site that makes reviews would be convenient if they could review the forum and the reputation of each site before making or submitting a review, it is more convenient, so they do not earn a bad reputation.
Here you can even understand how the casino review site objectively presents information, or does it write custom reviews for money. If the data of such a site at least approximately corresponds to the feedback from BTT, then you can trust this site. Because it is in BTT that I think the most objective posts are from direct casino users.
And it is worth reading about 100-150 recent posts in the topic about the casino and you will get an objective picture of events.
There are casinos which have reliable reviews from those first-hand experience of satisfied players. Most of these kinds of review is legitimate since it's have tried the quality of service and is talking from experiencing it maybe for a short period of time or even a long duration already. Many casinos has still verified reviews which the newbies from gambling could take some advice from. However, there are also gambling websites that pay people just for the sake of leaving a good review on their site. It's either a sponsored review incline with the casino, or a paid review in partnership with them.
There are also people who advertise because they are paid. In fact, there are already many posts here regarding that matter. They specifically call it 'shilling' and it's also happening in gambling industry not only in coins. Hence, people should really make an in-depth research before getting into it. Just like what you have said, it's a good idea to read even hundreds of posts regarding site reviews just to make sure they are unbiased and completely objective.
I think that the information about the casino in the topics in BTT is quite objective also because those players who write posts in the topics have the appropriate ranks and merits and it is unlikely that such users of our forum will write something biased. Maybe, of course, one of these users will do it, but the vast majority will not.
And when reading a topic, posts from beginners and low ranks can be skipped, not read, especially if it seems to you that this is a custom text and this user himself is paid. Then you can't trust him.
But, after reading what they write in the last 100-150 posts of a particular topic, you can definitely draw conclusions about this casino.
