Hey fellas, slaman29 tagged me so just chipping in.
My opinion in these situations is always the same - if a bookie takes the bet, they need to honor the bet.
They have many levers to pull - they can suspend markets, limit the bets, ban accounts.., it is their responsibility to protect themselves.
It's incredibly hard to prove match fixing, and I feel it's the wrong way to approach this case. Was Loris Karius bribed in the Champions League final then?
In amateur leagues all kind of bizarre things happen all the time, and yeah - fixed matches are surely more common. But if somebody's killing you with big bets in Finnish amateur leagues it's your job to find a way around it if you still want to offer these markets.

Regarding the arbitration - it's my opinion that it needs to be a team of 3-5 people, not a single arbitrator.
Hello, thank you for your opinion.
I guess after voicing it, the "bookmaker side of the argument" will not accept you as part of the arbitration panel

After all, you did not bring up the whole "you are Ukrainian, there are Ukrainian players in FC Futura squad, you are guilty, lets take your money" or the "you are betting 40+ thousand on Finnish lower leagues, you are rich, you are guilty, lets take your money" arguments.
For me, it makes much more sense to bet 40k on a Finnish lower league football, following the smart money, than putting even 1k on a roulette table, where the probability is clearly against you.
