Thank you for your bid.
As you already know, CL is often changing their code in order to prevent spamming, multiple ad posting and excess flagging. Considering you wrote the script more than a year ago, before any payment is made I want to make sure it is still working by running this simple test:
I will give you an ad for you to post. You will send me the link for the ad and I will try to take it down. If you are able to prevent deletion for 72 hours while I flag it from multiple IP's, then your script is working and I am interested to buy it.
Please let me now what you decide.
