You can block her if you don't want to participate in her auctions or let her participate in yours and if you won something from her and didn't recieve it you can request your credits back and flag her so Listia knows she is auctioning things off but not sending them. I'm an honest person and I really have no respect for people who do this, as a new Listian I ran into a few people like this and it really made the whole experience very unpleasant. Stop wasting peoples time. Go away! ~Charlotte~
