This is headshaking heheheheh. It appears that if you want your wallet to be safe and to not be included in possible sanctions or on a list of possible sanctions, it might be a good choice to avoid Bybit, OKX, Kast and Redotpay. There were rumors that wallets were noted as high risk by blockchain analysis companies after making deposits and withdrawals on HTX, the exchange of Justin Sun.

I don't know why this is a big deal to you; many nations, organisations and international blocs designate Hamas and what they represent as a terrorist organisation. However, this is not a debate of whether they are or not, but common wisdom for someone not to fund them through a traceable means, which is logical.
Those exchanges are well-known centralised exchanges, so it's natural that Hamas's funding and privacy would be known and could be frozen.
