I've been posting on CL for roughly 1.5 years, and have acquired almost half of my customers using this method. I post 6 ad's per day (because people spam and the ad's get buried quickly), spread out throughout the day. Between two accounts I had roughly 160 ad's that I use to renew daily, which took months. One morning this week I woke up to renew an ad, and all my ad's were flagged. Now, when I create new ad's, one account they get flagged immediately, the other account, sometimes they stick sometimes they don't. Has anyone experienced this? Thanks in advance.
