All I know is I buy more cards/items from Net54 members than I do from eBay. There is a lot less chance of problems when buying from fellow members. I make TTM payments and that does not happen on eBay anymore, plus I have had several members send the item the same time I send out the $. That would never happen on eBay.
As far as bumping threads, yes we have one guy who bumps his threads way more than the rules say but he is old and probably forgot he just bumped it the day before.
