Hello to everyone, this is my first post. I'm sorry to bump an old thread but.....

I have an aquaintance who makes his living selling spiral copper tubes to "vitalise" water and (obviously) believes all sorts of rubbish. Now, I'm unable to convince him of the idiocy of his beliefs about water (he "knows" the water passing through his "vorticies" tastes different etc etc and he has even convinced a top London restaurant to install his "equipment) and not many people I know take him seriously on that subject, but, he is now, using the ESA Hale Crater images, getting people to take seriously the whole "Mars Civilisation" baloney.

The trouble is that no matter how many of the ESA 3D "in perspective" images I examine I am unable to find any with similar "compression artefacts". I have read through (most of) this thread and, although people have posted links to other pixellated photos, none look anything like the artefacts on the Hale image/s. If someone could find another image that contains the same effects I would be most grateful. (Of course, if the image was of somewhere on Earth that would be even better, but I suspect that the characteristic effects only occur due to the particular processes through which the ESA images have been subjected.) Surely there MUST be some if all the "in perspective" images were produced the same way? And if not, what is special about these?
Being reduced to repeating "it's just compression artefacts, stupid" is not very convincing.
Please help me in my small fight against the forces of darkness

Thank you in advance.
