Apparently you are under the FALSE impression that by using TOR, a paid annonimizer (IP changer) like Hide My IP or even a browser add-on that your Origin can not be traced.
As your application or plugin is running it goes through a proxy or network of proxies and is encrypted. Even though the IP being displayed is from the last proxy, leaving the EXIT NODE and upon reaching the website your real IP address will be recorded.
The only way for a true encrypted anonymous posting or message at it's destination-- the website must be a a SECURED website, which would appear in blue at the beginning of the address bar, like at a bank or Facebook. Even with a bridge encryption extension from the exit node to the website, the site has to be able to encrypt it.
Topix is not in anyway shape or form encrypting your REAL ISP..They are not set up for or care about your anonymity.
Therefore, A simple JOHN DOE Complaint & Summons filed in any DISTRICT COURT and upon issuance of a Subpoena TOPIX must turn over the IP address attached to the POST Permalink.
Having the REAL IP address in hand and another subpoena based on your carrier, Comcast, Century link, etc. they will have to comply with the subpoena or be held in Civil Contempt unless they are able to quash the subpoena.
Having looked at several of your posting your walking a tight rope with defamation laws (examples) naming names and releasing secure, private information about a private citizen can COST you big..Any equity in your house? An extra car? money in your savings account?
One of your posts really raised an eyebrow when I read it and suggesta you have some inside knowledge that only an agency would know...Like a person using a food shelf and "take their daughter to go get something to eat" narrows you down to a few select people in that town, guessing North St. Paul.
This "leaked: information is cause for the dismissal and penalties of against that charters organization for leaking that information...To my knowledge--that being you.
That charitable group is run by LINDA ZICK and DAVE ZICK. Maybe a City employee or former City Managers wife? Chances are it is a city employee.. How do you fit in...Just the will to track you down is all that is needed. Your foolish if you think your invisible.
Conclusion. You are either one of the afore mentioned people or they leaked it to someone else who told you this private information.
If I where you I would be very careful what you say from this point forward. You have been forewarned.
Too bad fool, only a fool would try to track a ISP, and I don't care if about oil can henry's anyway's it's for old ladies an loser's like youself.
