It could be that they're just shitposters making posts to get paid (I haven't checked their signature spaces); it could be that they're trolls; it could be that they've got their own gripes against sportsbet....who knows?
It can be raising voice against all the casinos in general too about their false terms and conditions. There are some people taking the issue so seriously and trying hard to defame sportsbet but there are some people too who are only after the false terms and conditions of different casinos. There are something else too. I think you are not so active in reputation board anymore.
