I used to use the Topix blog frequently, but I had trouble with computer slowing down and spam/malware. Google search described some serious problems with Topix ads and pop-ups which may contain malicious code.
I believe several of my devices were damaged after visiting Topix Forum.
Also I had forums removed with no explanation. I tried to do a good job moderating. I never said anything that should have resulted in that action.
I hope they can clean it up and make it a safe and useful site for everyone in the future.
