You are insufferably thick. This has been explained to you several times now - as a courtesy, I will attempt once more to simplify things to your level.
You rent IP space owned by a provider. The IPs are not yours, and whenever someone runs a WHOIS to check the IP they will see the provider listed as owner. You, and what you do with the IP, are irrelevant.
If said provider hosts a client that sends spam and earns an SBL from Spamhaus, then typically only the spamming IP will be listed for the first offense.
If the provider doesn't bother to remove the spammer, or makes it clear that they are willing to sell to spammers, then the SBL will be extended to encompass entire IP blocks. From the starting /32 (one IP), to /28s, /26s, /24s, and so on.
You, and what you do with the IP you rent, are irrelevant. Because the upstream provider is willingly selling to spammers, large amounts of their IP space are marked in the SBL. You simply happen to be a casualty of collateral. If this inconveniences you, then you should address the issue with your provider. Or move to a legitimate host.
Spamhaus doesn't know who you are, and they are not to blame for your problems. Your provider is to blame, and if you insist on staying with a provider that won't keep their IP space clean, then the blame lays with you for being too stupid to leave.
