Is it illegal for residential property to agree to blacklist?

Property can publish the arrears information within the scope permitted by law, but if the owner's personal information is too detailed, such as name and address, it is suspected of infringing on personal privacy and will also bring security risks to the owner.

It is not illegal to post residential property. Because the property only informs the owner of this matter, and I don't want to or can't find the best policy of the owner. Of course, if the owners' meeting or the industry committee agrees that the property company must adopt other methods, then the property is suspected of breach of contract and will bear legal responsibility.
