That's clear for us here, regulations in coins.ph was really emphasizing a strict rules against gambling, because of an issue of legality.
However, the accusations should be supported with strong evidence if being suspected. For those traders with involvement with illegal gambling activities, better stop or else you'll face charges against them or possible sanctions.
Coins.ph is the number one and most preferred local exchanger in the Philippines I don't know if they are really that good at tracking users with transactions on gambling sites since they have millions of members but I'm sure they have a team that does this in the Pilipinas section I read some members here getting their account restricted for a gambling transaction, but I doubt if they will go to court or put you in prison they will only restrict your account.
