The subject of actually posting a negative review is a good one. I completely agree with your statement above and encourage the sub and the Domme to work out any negativity privately. Once something is posted online, it often can't be taken back and yes, it can cause damage to a Domme's career.

However, issues that involve safety are another matter entirely. If a Domme is unsafe and doesn't appropriately acknowledge the transgression when confronted with it, then that may be grounds for "outing" the behavior with a negative review. Just my 2 cents. At some point it becomes a public service to let others know about serious issues regarding unsafe play.
