most threads end when posters are finished talking. even preposterous threads die when posters decide to ignore them. other threads last a longer period of time because certain moderators indulge in personal insults. they egg on posters then they closed the thread down or move it to chit chat. it is obvious certain moderators have power issues in their personal lives or trading lives which carries over in their positions as mods. most likely they have difficulty pressing the enter/exit butons for trading. deleting a thread or moving it to chat helps to cover personal inadequacies or prejudices.. it is unfortunate even in chit chat certain moderators close threads. chit chats obviously should be held to very loose rules of conversation. some posters don't exercise much disciple in their speech. some mods unfortunately act similarly.
