No, you didn’t.
You started a thread with specific “how to” information about how to cause harm to someone’s computer. There was absolutely nothing in it about how it could be defended.
There were two things listed in your post. The first was explicit instructions on how to make someone’s toolbars disappear so that “They’ll spend a day trying to get their tool-bars back.” The second was how to screw up someone’s email while they were traveling overseas so that they would not be able to access their email at all until they returned to the US.
Your post was purely malicious in its intent, and contained exact step by step instructions that anyone regardless of technical skill could follow. While we do allow some discussions of illegal acts, we generally draw the line at providing detailed “how-to” type information.
By comparison, while the nuclear attack scenario does contain a general outline for an attack, it does not contain complete step-by-step instructions on how to commit an act of terrorism, and also has the intent of asking how to prevent this type of attack, where your post was just sharing how to do something harmful with absolutely no intent about how to defend against it.
Max_S linked to the appropriate rule (illegal activities). The bit about VPNs in Max’s post do not apply. There was nothing about VPNs in your post.
