The review troll is often controlled by greed or is somehow connected to a scam. In most cases this person will try to discredit you and your integrity to dicredit the review itself. I had a single post where 22 scammers came out and harrased me to the tune of 208 comments over a 9 day period of time.
Their goal was to make me retract my scam review, discredit me, or intimidate me into shutting down my blog. None of them had more than a fake name, movie start gravatar, and an affiliate link to the scam program.
Here is what I put out in regards to the attack while not addressing the trols other than answering valid questions with no emotion.
THIS REVIEW IS UNDER ATTACK
There are people in this world who take joy in defaming others to forward financial gain. These comments as you can see are far stretched and often repeat the same attack lines from troll to troll. Our post are done with a combination of research, insiders information, and experience stretching back to 2003. I will not be intimidated and ask you to not be intimidated either. Thanks for your time please comment below.
The results
I could have deleted the controversey and blocked a ton of accounts but I only deleted the accounts that were vulgar and used profanity. In the end the FTC shut down the program but the controversey drove over 330 people into one program, sold several info products, and generated more than $900 in sales commissions.;
I once read it doesn't hurt to write down your feelings BUT DON'T POST IT! Just get it off your chest, have a cool down period, and then go back and construct a reply as in your example. What you would say in the heat of the moment, you most likely wouldn't say once you peeled yourself off the ceiling and looked at the comment objectively.
