Hey, check out AT&T’s new Terms of Service clause:
AT&T may immediately terminate or suspend all or a portion of your Service, any Member ID, electronic mail address, IP address, Universal Resource Locator or domain name used by you, without notice, for conduct that AT&T believes...© tends to damage the name or reputation of AT&T, or its parents, affiliates and subsidiaries.
In other words, if you talk smack about AT&T, you’re out on your ass!
