Many many moons ago, I was banned from a local freecycle group; the sort that was email only. Each week an list of offers and wants was emailed to all subscribers... but every now and again, in the 'wants' list, someone would have a listing along the lines of "Wanted: People to boycott such and such antique shop for having an old Roberson's Jam Poster on display. I asked them to take it down and they refused. So please boycott this racist shop" ...every time i saw one the "Wanted, people to adhere to my moral code." listings, i couldn't help but reply with a piss take... it took about four for me to get banned.
