    Any program that can read a PDF obviously can manipulate it in any way it likes. Thus, this is nothing Adobe can do anything about.

  2. Digital Signature does not validate

    Your documents have the NeedAppearances flag set to true. This makes any signatures therein questionable as it instructs any PDF processor to "construct appearance streams and appearance dictionaries for all widget annotations in the document". Thus, chances are that the signer saw something different when signing than another person viewing the signed document, in particular if a different viewer program is used.
    If you set that flag to false (or don't add it at all), Adobe Acrobat recognized the signature.
