Am very reluctantly selling a high value designer item (a handbag). I listed it last night and within 2 hours Ebay had removed the listing, saying along the lines of they think its fake. I am fuming! It is not a fake and I clearly state on my ad that I have all the relevant documentation that proves it is genuine, and put pictures of the said documentation on my ad, I really can't do anymore to prove it.
Yet there are several other items similar to mine, which have been "allowed" to remain 
Not sure what to do, but I badly need to sell this item, I need the money sadly as had some bad news work-wise yesterday :(
