No, there is no option for that.
Guess it depends on what you are selling. If it's pirated software, you will find me flagging you too, not that that is what you are doing.
I can only speculate as to why someone has it out for you. If someone is constantly flagging you and you are not breaking any of the rules, you should contact Craigslist. It takes more than one person to flag an item to get it removed. One person could flag an item 5 times but I think it only counts as one.
If you would like to contact me directly and send me a link to one of you postings I will try to give you a better idea what could be causing the flagging.
I shop on Craigslist daily - LA, Ventura and Santa Barbara Counties in California. All 3 of these sites are open 24/7 for: For Sale-Wanted/Computers by owner as I'm always looking for great buys for our clients, and I do FLAG but only when I find people selling pirated software or selling Microsoft software that obviously comes from a Microsoft Action Pack where it is against their policy to sell or put on computers that are not used by the authorized company who purchased it from Microsoft.
We are an authorized distributor and partner of Microsoft and we do it by the book, and we are also a Authorized Microsoft Refurbisher.
I would be happy to help you further if you reach out for help. That's why I'm here on Yahoo Answers
