AOL has threatened legal action against authors of World Wide Web sites that make copies of hacker software available for downloading, including the now-infamous AOHell, which can be used to send mailbox-disabling e-mail bombs, among other things. Spokeswoman McGraw said she didn't know whether the company had prosecuted anyone for using or distributing the program.

...the arrest and firing of Morgan appears to have sparked some changes.

Since April, the company has been including a warning when subscribers receive e-mail or messages telling them not to give out any financial information, even if the person sending the message identifies himself as an AOL employee.

AOL spokeswoman Kathy Johnson, speaking from the company's Vienna, Va., headquarters, said she did not know whether the change was a direct result of what happened in Jacksonville.
