In my humble opinion....
1. I doubt this had anything flammable washed in it, I have not heard of many people who are THAT stupid in a long time, but who knows.
2. I really doubt this was faked.
3. I also really doubt something was dropped (hard) on the top of the machine, causing this type of damage.
I'm 99% sure that all front load (vertical axis) machines going back at least 15 years, have a plastic outer tub. So if the inner drum were to fail as I suspect this one did, that would cause the outer drum to shatter into many, many pieces, making it "disappear".
What I think happened is: this washer has a load of what looks to be towels (heavy) and it was probably at or near it's max spin speed. I suspect the seam/weld/joint on the stainless drum then failed, causing the seam to separate. (The stainless drum is stamped from a flat sheet of steel, which necessitates a joint or seam.) Then due to the weight (G force) of the damp towels against the drum at this high RPM (very high at this point) the seam gap widened, causing the outside diameter of the drum to expand and deform quite rapidly. The spinning drum then hits the plastic drum destroying it, then the motor, the suspension, cabinet, etc. Instant carnage.
I would also dare to suggest the "weakness" in this seam is most likely due to a problem during manufacturing, for instance a poor or weak weld.
