I have a “client”, mostly a person interested in my work.
Which asks me if I can do “x” image, to which I answer yes.
He insists that he wants me to make the image without him accepting the offer, to see if I serve what he wants (and so, I assure my future work with him)
I sent him a picture of half the job, with an “watermark” in the shape of an octopus covering half the job, and now he insists that this is not the way I should send him his request.
How can I block the “gentleman”?
