It makes me wonder if a powerful malicious agent can devise a complex operation (planting people in several key places) and wipe out most of the databases of one these places. It would be interesting to see what would it happen if suddenly all of twitter of facebook is deleted , puff!, gone in a second.

Actually deleting stuff at these scales takes many, many days if you don't want it to be trivially recoverable.

You can't delete that much data in a matter of seconds digitally. You need to physically harm the hardware.

Wipe the encryption key of your SSD, small amount of data to wipe, and the whole SSD is unrecoverable. FWIW at least OCZ SSDs have an encryption key flashed into it even if you didn't turn encryption on. Putting a new firmware on it can wipe this key and make your old data inaccessible. Source: got a buggy OCZ firmware that failed to make the device appear on the SATA bus, only way OCZ could fix it was to install new firmware which wiped the key and hence my data was unrecoverable.

Interesting point. I stand corrected. Not sure why I didn't think that way.

I recommend you watching Mr.Robot :)

I watched the first season but got tired of the constant morose attitude of the main character. Does it get better?

[Keloo]

the mood of the character doesn't change. The plot is quite good though.
