I have a fuckload of banned accounts too. You don't need to do anything fancy. Go through your phone as a hotspot, and hit airplane mode to grab a new IP. Then, generate a new account with a burner email to verify it. Grab a new IP every time you switch accounts. Throw up a couple of easy point generating posts on default subs, and let them sit for a month or two after you get a couple thousand karma. You need to plan ahead for trolling.
