eBay came pretty close to hitting "the last straw" with me a few weeks ago when they gigged me for listing a prohibited item, removed the listing, and docked my "policy compliance" rating down to "low" (which endangers my power seller status and makes my fees higher and goes on my permanent record in case they ever want to kick me off one day).  The offending listing was not in fact prohibited and I was not in violation of any policy whatsoever, but attempts to get a human being to use a brain cell on this matter were doomed.  Here’s how it worked:

Here is the glorious computerized, search-form-enabled, utterly freakin’ stupid and illogical manner in which my bath salt listing gets removed:
