I actually had to block someone who was pinging the dragons with art pinglist the other day - I was getting a ping almost daily to their art sales thread, where none of the dragons were selling but they kept adding more (and they were always mostly naked so not really something I wanted to see on a daily basis). I feel like there should be (or maybe there is?) a rule like "for dragons with art shops, only ping once every x amount of days. make a personal pinglist if people ask to be on it and ping them whenever you add a new dragon".
