I tried to send XRP to one of the gambling sites I'm using, but I was prompted with this message.

Therefore I'm suggesting everyone especially from the Filipino community who are constantly transacting from coins.ph to a gambling site/s or vice versa. The BSP is already monitoring us, and if we submit the information and put a gambling site as a recipient, we might be sanction as gambling is illegal in our country and it's part of the TOS of the coins.ph that sending coins to a gambling platform is prohibited.
you may refer to the complete terms of services of coins.ph.
https://site.coins.ph/user-agreementProhibited Uses include transactions or activities related to:
(c) Gambling: Online gambling, lotteries, casinos and informal gambling, gaming operations, sports betting, and other games of chance and forms of speculation;
While it is always a good thing to listen to other users warn about their experiences in other websites, at the same time how long has that been on their terms of service? After all I suppose this has been there for a long time but it was not enforced and now that they are doing it people need to take care of not getting their accounts blocked since they are violating the terms of service which are incredibly clear, so from now on send your coins to a wallet you control and then to a gambling platform to avoid this to happen to you.
