Some people might not know these sites but I think you don't need to post this since a lot of gamblers here already know where to go. Another thing is that there are a lot of signature campaigns here on gambling sites, people could just click on it.
But I think that it is just fine to have these options to have a breakdown,
As for me, I prefer to have to look in this kind of list to have recommendations from another user. This way, I can have more options for a better website to choose from. Also, many users here might prefer the same.
There's nothing wrong recommending some gambling sites that one thinks are trustworthy. At the end of it, you are still the one who will choose if you will try other sites that someone had recommended. Indeed some gamblers prefer to look for more opinions and reviews by others before trusting and trying a gambling site to make sure that it has a good reputation.
Even though I don't easily believe with recommendations, it's still good to have more options when picking the best online gambling. Although I usually stick with the one I know and have tried before, there are people who are looking for recommendations, especially new online gamblers.
