That makes no sense. All you need to do is send the Monero to a new address. They can't block the addresses they don't know, and they can't see the address that you are sending it to. I do agree with there being some danger to it, but not the one that you speak of.
It’s true that Monero addresses can’t be tracked, but when you swap Bitcoin for Monero on a no-KYC exchange, your Bitcoin address can still end up on a blacklist.
YouThat is true but you are never supposed to reuse a Bitcoin address
. Therefore,
so this is not a real concern but rather an user error.
Do not reuse addresses.
