"Maybe your price is too low or your bike is too good looking"
I think there is someone in the local area, perhaps selling a bike of his own, that doesn't like me listing my bikes.
I have had a lot of trouble having CL listings being removed for my 2008 F800ST as well. I did some research about it. I may have to have a new email address and new CL account.
Once you list an ad, supposedly you should open that ad in a window 20-30 times. The logarithm looks at the ratio of opened (accessed) listings vs.flagged. That is, if you just list it and it gets flagged it will be removed, but if you list it, open it in a bunch of windows, CL servers don't differentiate between ISPs, so you listing, then opening your own ad looks like 20-30 people opened it, had no problem with it and then, if flagged, the flag may be ignored. However, that's not working for me.😠
I've had to shorten it down, a lot. I tend to be detailed. My asking price was not too low. Eventually, I had to strip the ad down to almost nothing to get it to stay up. Even fewer pictures than normal.
