There are a few ways companies can protect themselves from spammers and protect their client's identities. Since anti-spamming laws now protect the rights of companies and individuals from harassment, it is much easier to find and sue a person who hacks into a company's database and steals important client information. Using this information is a crime and could result in heavy fines and jail time. Companies have to protect their client's personal information in order to remain loyal and competent. Many companies have highly technical spam blockers and firewalls that can assist in keeping spammers out.
