I did a quick check on the forum and they seem to not have an announcement thread here so there is not much we can do on this side, perhaps you should try posting this on casino.guru or askgamblers, they might be able you and mediate the issue you have with betplays.com and hopefully get the issue resolved.
Even if the gambling site have announcement thread on this forum, this type of issue can not be solved on this forum. He needs a mediator like casino.guru or askgamblers that you mentioned because the gambling site will not want to post the anything related to the issue in this forum because if the user's privacy. Also, it is worth knowing that in most cases, it is true that the gamblers have two or more accounts. This on e can be different but if 99.99 to 100% cases are found that the gambler is truly guilty, I think this will not be different.
