I know Calibre can remove DRM, but it seems that Calibre does not remove things like watermarks, references to the buyer by name, etc. Now maybe I can try to find those manually, but that is an error prone process. Plus, what if they embed a unique digital signature that ties back to me? I understand that this is a very uncommon practice, but I do not want to find myself in a bad place.

I suppose the only way to remove a digital signature of any sort is to buy two of the same e-book by different people, diff them, and remove anything that differentiates them.

Is there any tool that does this or automates the process? am I being too paranoid, and this is not a real threat?

From what I gathered Amazon is the only one that includes an identifier. Look for a string starting with "atv:kin".

The DeDRM fork removes it: https://github.com/noDRM/DeDRM_tools/blob/bf2471e65b1f52bb5292caeba70a9aea31bf6653/DeDRM_plugin/mobidedrm.py#L254
