I didn't used to disguise it but recently a company on another forum went beyond the pale to stop criticism levied at their claims for a lucrative performance product.
Stating an opinion that a company's product is crap is fine, until you reveal how it is misleading in detail by presenting and comparing facts. Even then a corporation can't prevent reasonable queries being put, nor does it need to respond.
However the corporate tactic changed when I began to cop personal threats and abuse from one of the directors. That spilled out from ignoring DMs to real life with personal calls and voicemail on my private mobile, and other detailed threats based on private investigation into FaceBook pics / activity, twitter, YouTube, LinkedIn.
Personal shock turned really nasty when the company's legal team threatened to prosecute me unless I apologised to this director and promised not to mention him, company, product again. So yeah shepherded for blackmail in the form of a criminal and civil suit for lost company business because I allegedly besmirched a director... who also threatened to kill me. Just don't need that.
In so far as a reliable chain of evidence the rego plate identifies you by linking your vehicle and the comments you make as well as videos you post online. Determined nutbags whether rich, poor, individual, corporate or government, may use that morsel against you for a range of unscrupulous activities... only for the duration that the internet exists.
