Looks like he has been found out,some of the ads have been removed already.
The adds themselves could also be stolen from previous people selling the bikes. If you look in the backgrounds of the 2 remaining ads they are in totally different places (one against a blue shed with horazontal boards, one against a dark brown shed with vertical boards)and the format of the adds are different.
In general people stick to the same format when they sell there stuff – same text sizes, colours, fonts, layouts etc these are totally different sugesting they were done by diffrent people.
