I guess I should of shared this information a long time ago, but it's based off of how old the account is. For me, if the account is over 3 months old nearly ANYTHING I post on eBay hits it almost instantly after submitting. Just the other day I used one of my marinated accounts to sell a $3,000 Dell XPS desktop.
I'm not sure if feedback helps. I'm sure it does. I always build up my feedback to 10 on any account I sell on. I use backup accounts to purchase $9.99 auctions from the account I'm wishing to sell on and then close the auction early to the highest bidder.
So ya, 3 months old / 10 feedback = my magical numbers.
10 hours ago i listed items and nothing shows up, looks like they are getting reviewed, nothing vero or that, all legit stuff, but a new account and 20 + items listed within 1 hour.
Strange this, ebay calls me @ 3am to verify the account! I'm in bed and don't answer, waiting for the "restricted account MCO" message to come through any minute.
