and falsified other information to circumvent CompuServe's anti-spam measures. Due to the high volume of email, CompuServe claimed damage to its servers as well as money lost dealing with customer complaints and dissatisfaction. CompuServe also extended its damages claim to its subscribers who spent time deleting unwanted email. The court held that Cyber Promotions's intentional use of CompuServe's proprietary server was an actionable trespass to chattels and granted a preliminary injunction enjoining the spammer from sending unsolicited advertisements to any email address maintained by CompuServe. Cyber Promotions' persistence in sending email to CompuServe's servers after receiving notification that CompuServe no longer consented to the use weighed heavily in favor of a finding of trespass. A trio of 1998 cases in the Eastern District of Virginia involving America Online more firmly established the use of the trespass to chattels tort as a spam-fighting tool. In America Online, Inc. v. IMS, the court held that the owner of a marketing company committed trespass to chattels against an Internet service provider's (ISP) computer network by sending 60 million unauthorized email advertisements to the ISP's subscribers after being notified that the spam was unauthorized. The court found that the defendant, intentionally and without authorization, caused contact with the plaintiff's computer network by sending the bulk email messages. Such contact injured the plaintiff's business goodwill and diminished the functioning of its computer network. Similarly, in America Online, Inc. v. LCGM, Inc., a company engaging in pornographic website advertising sent a deluge of spam to AOL's customers, and, in so doing, also forged the AOL domain name in an effort to trick customers into opening the emails. The court once again held that a website operators' transmission of unsolicited bulk emails to customers of an ISP, using the provider's computers and computer network, constituted trespass to chattels. In America Online, Inc. v. Prime Data Systems, Inc., the defendants sent millions of spam emails to AOL subscribers advertising computer software programs designed to facilitate bulk emailing by allowing users to harvest email addresses from the plaintiff's member directories, chat rooms, and electronic bulletin boards. The defendants also used technology designed to avoid AOL's spam filtering mechanisms. The defendants frequently used false and deceptive "headers" in email messages to make it appear as if AOL had sent the messages. The increased demand on AOL's servers resulting from the spam caused substantial delays of up to 24 hours in
