Composite Blacklist which is a part of Spamhaus (also an IP blacklisting service), is a DNSBL blacklist. CBL lists the IP addresses that show activities such as being a spambot, being an open proxy SMTP server, or being a spam server.
We can assume that it should be similar to other popular DNSBL services since like some other blacklisting services. CBL listing criteria is undisclosed by CBL.
If you are still facing the issues with the IP removal after following the above steps, you can check these steps.
