I think he means casinos that have managed to achieve a good reputation over a long period of time, especially platforms that run promotional campaigns on the forum such as longstanding signature campaigns and betting competitions. All of these platforms have a good reputation and I believe the best crypto-based platforms are represented here on the forum.
In addition, members with a good reputation run casino review sites such as casinoguru and casinocritique, which can be trusted at some extent.
The long running signature campaigns for gambling casinos are one way to look and judge the reliability of the casino but we cannot only judge on this basis. There may be a casino that is a good reliable one but not running the campaign here and there may be scam casinos running their campaigns too (as we experienced with 1xbet ).
I agree with you that all reviews should be treated with caution regardless of their source, but at the same time I cannot deny that the forum is the best space to get honest reviews. It is more effective if the person is at least familiar with the mechanisms of the forum and the features of its use in order to be able to distinguish between the different reviews.
You can get good reviews about the casinos here in this forum but i will suggest to get opinion from different forums and platforms and then develop your own opinion whether you want to gamble on a particular casino or not. Many people do not know about this forum and they only check the reviews from different casino reviews sites and they ignore the fact that those reviews can be manipulated / paid ones too.
The picture looks very bleak from your analysis. In general, I am convinced that the diversity of sources may not always be useful and inevitably increases mental distraction, and on this basis I think I have chosen the most efficient space to obtain the most objective reviews possible. The forum provides a space for exchanging opinions and experiences about different platforms, which helps gamblers and investors to make perfect decisions.
In general, Bitcointalk can be a good place for research and discussion, but it is important to do personal research and analysis as well. On this basis, there is nothing preventing us from relying on side sources, which are in turn confirmed by the forum itself. That is why I mentioned in my previous answer two sites run by honest members here on the forum who are in direct contact with the platforms they list. These sites have often been able to cooperate to resolve outstanding issues between a user and one of the platforms they list. Many platforms have begun to avoid getting a negative rating on these sites.
