When trying to contact a seller about a motorcycle adjustable CDI unit and its adjustment, it involved the use of the words "Advance" and "*bleep*", as technically descriptive of when the CDI unit delivers the ignition spark in relation to the position of the piston in the cylinder.
However, eBay's AI PC analysis of this latter descriptive word, views it as a personal insult from the writer to the seller! Abbreviating the latter descriptive word, by removing the "a", blinds the AI and yet still conveys the technicallity that you are trying to convey.
I hope this helps those who have similar problems, with eBay AI PC rules.
