Same Whois on All Domains – Is this bad?

I currently have a small network of ccTLD PBNs running. It's not possible to register WhoIs protection for these domains (or possible but very hard), so I added random info on the WhoIs.

However If I check the WhoIs for any of my domains I get the same exact info. The name and address of the person who owns the registrar. They probably did this to protect the info of the owner.

Is this bad? Even though it says that they are associated with more than 300k domains.
