Cyber Promotions sent LOTS of unsolicited, commercial email to AOL customers. They forged the email headers. They used third party emailers to get the mail into the AOL system. They caused a lot of hassle for AOL's computer administrators. Cyber Promotions sued AOL.
AOL attempted to cut off all email contact with Cyber Promotions. AOL mail-bombed Cyber Promotions, causing two ISPs to cancel contracts with Cyber Promotions. AOL sued Cyber Promotions.
Is AOL's mail system a "public space"? A company provides a public space if it
No. Strike a blow against SPAM and against free speech.
With this definition of a public space, are not all of the real spaces we communicate in private, and therefore censorable? What about the proc-CDA page that was censored by its ISP (http://members.iquest.net/~jaelb/antiporn.html)?
