So, go level up on how browser identification works or call it day.

I was back to anonymous posting and all was good. All I had to do to get around the ban was clear the name field, exit the troll thread in question, and stop fucking around. A little more sophisticated form of mod action than by previous ban, but not by much. For the lutz I posted something innocuous with their name and was promptly banned for using that name.

Much more recently, couple of years ago, was the last time I was ever banned. That required more than just a 'router reset' to fix, but it only took me about twenty minutes to figure out with some browser changes. The last time I was righteously banned from 4chan for my own bad behavior was way, way, back in the day when you completely lost access to the site, not just posting privileges. For that, you'd need to work on your browser so as to unidentify yourself. I suppose it's possible they're running an anti-troll harassment package the makes the site hard to use for the troll in question.
