Please discuss if you think this punishment is too harsh, or if it's appropriate, due to the gravity of the situation.
it really depends on his involvement in the match-fixing. I am sure they have criteria on whether someone who is involved in match-fixing deserves a lifetime ban or not.
Also, what is the impact of this case over gambling industry?
Why would this have an impact on the gambling industry? The gambling industry is very big and I don't think this incident will not have a kind of impact on the industry.
The FA thinks he deliberately do it and they learn about his pattern. While some just got a lighter punishment him was harsh though. But I think wasn't the first time where a player was banned for life.
I'm not sure if this could change something on gambling industry, but I think they are going to keep watching players who has tendencies in gambling involvement. Chances is that most of them are gamblers.
