If this is as far as you get in this post, just remember: online criticism will happen NO MATTER WHAT. And it will all be ok.
Earlier this year, a woman orchestrated a coordinated social media attack on my business and me personally. It left me gutted for hours. I could tell soon after she messaged me that she was attempting to get a rise out of me for social media attention, which was confirmed by the other reviews she had been recently leaving local businesses.
However, I was able to take (most) of my own advice and quickly diffuse the situation. I didn’t handle it perfectly, but I have absolutely come a LONG way from my early years as a business owner, and I am proud of my response to the situation and still stand by it.
