This is the scary part TBH. Seeing how they behaved here and which arguments they used/defended, you'd think they are just starting with their business.
Yeah. They did embarass themselves for sure by going back on their own words just because they didn't with certain viewpoints. They definitely aren't a scam site, but they will lose punters with those sort of behaviour.
If they are really here for 10+ years, they should know better than to say 'ooh, this looks fixed'. The lack of understanding of sports for a sports bookie is baffling as well.
Their evidence did it make it look like some of those matches were fixed though and they are a sports betting exchange(Not a bookie).
