I honestly don't mind it and here's why. For me, I always bookmark the for sale items I'm interested in. If there was something that I've been thinking about, but needed to do more research, or wait until my pocketbook feels fuller, I don't mind seeing the ads again and again. Then I might contact the seller and ask questions, but I still know it's out there. I'm very picky about what I buy and unless I have shot a gun, or looked through the same scope, I don't know how I'll like it once I get it. So leaving the ads up give me time to make a better decision before I pull the trigger and buy something. If there starts to be limits on how often sellers can list something, they might start putting their ads on other websites instead. Just be thankful we've got an enormous active community and leave it alone.
