Cloudbet should answer this because hiring shill cannot give any positive output on them but instead people will doubt about their intentions for doing this. They are old casino so they should know the consequences of the actions towards this and if many people will find out that they hired shills for sure this could bring them more criticism from people who doubt about their reputation.
I don't think Cloudbet is behind the shilling, though. It's an old casino, they have had so many campaign in the past, and they definitely know the forum rules. This particular ring of scammers or bumping farm just replies other threads to;
1. Increase post count.
2. Make their accounts undetectable to the snoops by covering their tracks in legitimate threads.
I checked this thread because I play casino and for me it is very important to check the reviews about casino. Not only positive, but also a negative one.
I saw here negative reviews about Cloudbet but they were delated too.
Do you thing that the team of Cloudbet hire somebody to post negative reviews?
May be it is competitors post here negative reviews because casino is popular and discussed.
As for me I think that there is no reason just to hire somebody and pay money for posts because this thread is at the top and actively discussed without any posting.
