That means that it involves the human being doing the postings, even if the platforms such as Facebook and Twitter are leveraged for commercial purposes. And there's the rub.
BusinessInsider carries the AP coverage of Jeremy Alcede. When he owned and operated his gun store near Houston, Texas, he used social media for marketing. Then, as the AP notes:
" ... after losing ownership of his ... store in bankruptcy, Jeremy Alcede spent nearly seven weeks in jail for refusing a federal judge's order to share with the new owner the passwords of the business' Facebook and Twitter accounts, which the judge had declared property."
Some are trying to simplify this new issue in law by recommending that social media personal and commercial accounts be kept separate. However, they misunderstand social media. Its very power comes from its highly personal nature. The personal Facebook account of the business owner, even if not combined with the company one, can be linked in the minds and hearts of followers.
My hunch is that social media accounts, both personal and commercial, will be classified as belonging to the business. The odds are that their value as a marketing platforms are too high to allow to be considered not part of the property.
