Online Casinos Without Online Presence/Community
From my observations, I think online casinos without online presence or community of users are likely to scam any user and get away with it easily, and it doesn't matter if they have a high trust rating, this is because when they refuse to process your withdrawal and the customer support is not responding or not helping, the user in reality have no place to complain that will force the casino to pay him of lose a great number of their users if not all...
Like for example, if a casino have a community on bitcointalk, and you are a user of that casino, at any time you have an issue with that casino and the customer support is not helping, bringing such issue to their community on bitcointalk will force the casino to find solution(s) immediately so that they don't lose their other customers in the case where they are the ones at fault..
But a casino without any kind of community anyway, if as a user, you encounter any problems and the customer refuse to help you, you are absolutely helpless, and complaining on forums where the casino is not even known won't help because it does not affect the casino on their business, they probably won't see your complaints, neither would their other customers do, so certainly, they won't answer and their other customers also don't know what is going on.. So it is best to avoid such casinos in my best opinion..
This is just one out of many types of online casinos to avoid, so let's make the discussion long, what other types of online casinos do you think gamblers should avoid? You never can tell, your advice might help someone in a short of long way.
I get where you are coming from but let me play the devil's advocate here. Trust rating should always be taken at face value and not be interpreted any other way. The matter with whether these ratings are manipulated or not is out of the question because if that is so then there's a good possibility that all gambling sites out there with an extensive community may as well skew the ratings to their favor. What I would highly suggest you look out for in a gambling casino is their customer service. A customer service that is subpar or non-existent is a telltale sign that something awry is afoot. Meanwhile like a post I saw here back then, if their customer service is great enough that even in forums like these they can help you once a complaint is made then that is a surefire sign you're in a fair and legit casino.
Well, in as much as I agree with you, I think you didn't get the original point of the whole discussion, me making reference to online trust rating is just as a corner stone laying foundation to the actual point I am trying to expose to the community.
Online casino without online presence simply means an online casino that have no community online where you and me and every users of that casino can interact with each other.
For example,
Stake.com have an announcement thread on bitcointalk, this ann thread also serves as a place where stake users can interact with each other.
Owl.games, Blackjack.fun, Freebitco.in all have announcements threads here on bitcointalk which also serves as a place where their users interact with each other..
On the hand, there are online casinos out there that do not provide this kind of means or facility for their users, which means their users don't know or interact with each other, such a casino can easily scam a user and other users of that same casino won't know about it because there is no means or place for the scam victim(s) to alert other users of that casino to be aware of leave the casino before they fall victim too.
I hope with the above explanation, you are able to understand the context of this topic.
