online laws

Several months ago I entered one message board thinking it would be safer than chat-no live interaction. After a month I had a group following on my posts and answers and thought it might of been a person or persons I knew but no real names were ever given-just aliases and they claimed to be from states where I have no personal contacts and I shrugged it off. Some things posted were down right nasty but I knew it was a public message board and those things happened. One day I checked website searches in my name through the net, I do it for professional purposes and I found over 300 websites in my name and some had personal information on them.
I did print them but never pursued except several where I contacted the web owners and asked to be removed from links and hoped it was a prank and would stop-I stopped using the message board and internet completely and shut my email accounts down because I was continuously getting spammed and pinged when I was on line even after leaving the message board and phone hangups happened at my work and home.
About a week ago I entered the same message board thinking whoever it was went away and I was called a stalker for entering this public forum and now I wont return even though I think my freedom of speech has been violated.
My question is in a message board where no real names are given and my alias is no where near who I am be in a legal entanglement with harassment and stalking laws? I never emailed threats, posted threats or purposely bothered anyone in the forum just answered and asked questions and I was never reported to the moderator and none of it was sexual.

Honestly, I can't follow the connection of the beginning to end, but there are harrassment laws that can apply even in anonymous situations. For example, if someone called your telephone number and made threatening calls, without even knowing your identity but intending to harrass you, that would probably be unlawful conduct. It probably will not matter that it was done using the Internet.

I can't answer your legal questions, but I'm curious as to how people found out who you are. I'm assuming when you say you searched the internet for your name, you mean your real name and not an pseudonym that you use for posting.

It's possible that they saw duplicate IP addresses. Static IPs, e.g. connection from work, makes surfing anonymously less anonymous since your computer may have been assigned a specific number by your office or your ISP. Thus, they may have known the same computer was accessing the forum but didn't know the real name of the person.
