Apart from the name being similar to the names of other casinos in the forum, there have not been substantial evidence to suggest that they are connected to another casino in the forum. I saw the thread where that claim was made by one of the forum user but it was clarified that they only got their license from the same place that another casino got theirs, that is not evidence of them being owned by the same people.
Sometimes they will have something in common like their license or in their codes. I don't know about Spinna.bet and any casino is from the same team of Spinna.bet but in the past, there are several casinos were detected that they are from a same team. Some are good casinos while some others are scam ones and they left the forum after solid evidence found and reported by community.
It is only bad if a new casino is from a scam team behind previous known scam casinos while with Spinna.bet, we have found nothing like that.
With Spinna.bet, welcome.
