Since Topix runs on its own servers, it is highly unlikely that the average layperson will be able to trace the IP addresses of the posters. Another thing that makes it even more unlikely that you will be able to track down who is posting about you is the fact that Topix does not require posters to register with a username, birth date and IP address. You simply type in an alias and post. You can change this on everything you post, if you like. Also, even though Topix will generate a random location in your area stating where you are based on the location of your internet service provider, simply resetting your router will generate a new location, making it seem as though more than one different person is doing the posting.
Also, donít assume that you can walk into any police station and they will get their best investigators on the case to find out who is posting about you. Unless there is threat of serious physical harm being done, chances are slim, mostly due to the plethora of cases reported. It is popping up in the mainstream news more and more that the postings on Topix are destroying peopleís personal relationships and sometimes, their whole lives. There are cases in the legal system between individuals/state governments vs. Topix. It is widely suggested that Topix require users to register before posting, making it much harder for posters to veil their identities.
