I am the idiot who bought this board 'used few times'

Where was it used, I wonder, on gravel driveway

Some People will say anything to get rid of their merchandise. Anyway, lesson learnt, will ask for hi resolution photos rather than rely on the owner description for anything I buy in the future. Photo of glossy top of board from a distance plus owner assurance that it is barely used will not do.
Do you guys think the integrity of board is in question when there are fairly deep scratches in the bottom of the board?
The last photo shows also my own board that I used more than 500 times over 3 years - if the one I bouht is 'barely used' then I should advertise my old board as 'brand new in exceptional condition' . Kitsurfers are a good bunch in general but watch out for wankers, they are out there too
