The first rule of holes is to stop digging.
I am always shocked at how often lawyers and their clients fail to appreciate that certain attempts to try to cover up an embarrassment will result in even more attention to the embarrassment. These people generally have no understanding of how the Internet works - which in this day and age is scary.
The Internet has many examples of this foolishness. (e.g. KlearGear, Suburban Express, and the Union Street Guest House) The result is always the same and it is never pretty for the entity that tried to censor the Internet.
The latest example took things one step further. Sundance Vacations is alleged to not have just made threats, but to have forged a court order. What could go wrong with that? Their story is told here: https://medium.com/technology-musings/sundance-vacations-from-scams-to-forgery-ae2afe64fce2
I have no first hand knowledge of this matter. You are free to decide who you believe. But if this is true, my prediction is that Sundance Vacations will have some serious regrets.
Any attorney that is advising a client on negative reviews posted on the Internet needs to have a serious conversation with their client about the natural and probable backlash that will come with an inappropriate response. Unfortunately, many attorneys fail to do this and their clients wind up paying the ultimate price. A good attorney has the confidence to tell their client not just what they could do, but also what they should not do.
