I know this user since jacksclub launched some time ago, means that this user is there even before the launch of jackbet.
Low chance that he is a part of jackbet, I was even thinking that he is trying to impersonate the admin of jacksclub by using that username.
There was also some other users spamming jacksclub chat to promote other sites, it does not mean that the users are the admin of the other sites.
I do not try to defend jackbet, just saying it based on what I know in general.
