there's a difference between decentralized transactions and centralized APIs for viewing on-chain data. a decentralized blockchain cannot block an address from sending or receiving transactions (without a hard fork - like ethereum did some years ago). however, centralized services (like binancd) run nodes which read and publish on-chain data (transactions and data, like malware, associated with them) through regular HTTP APIs. anyone running an API can choose to not allow access to data associated with certain addresses. it's their API and they can do what they want with it. the same way the youtube (insert platform) API could decide to block queries for certain channels or topics.
