Even if the software was purchased (rented) from someone, it still does not explain the usage of identical verification meta tags. It would be like buying a used car and using the previous owner's driver’s license to drive it (there might be a better analogy, but I cannot think of one at this time).
Could it be likened to a man who rented a new apartment. On relocating from the old apartment to the new, he left behind his beddings, home appliances, his documents (identity documents inclusive) in the old apartment?. If there were few matching meta elements, we would have said it's a coincidence and maybe only to aid search engines optimization. But in this case, it's almost verbatim.
Betting business is a risky one in nature, so it will be so damaging that one will not only undertake the risk of losing but also the risk of credibility of the casino owners incase of winning.
