Hi Peter,
I'm a member of several blogs and forums. There's something called "The Freedom of Speech" (at least in the US). Do you think all forum/blog members should sign their real name and possibly address, phone number, and maybe credit card number to each post?
When I was dissatisfied with a car dealer (who sold me a lemon car), I posted the information about my experience with them on several forums. But it was just
my opinion - I'm sure the dealer claimed I was wrong and they were right. I didn't include my real name, of course, because I was afraid they would find out who I was and would take some actions to ruin my credit rating or even threaten me.
In my opinion, it's good you found this site - your comments and replies may only prove your companies are legit and you care about your clients, which in result may bring you even more customers. If the admin had really contacted the first poster and the poster will not at least publicly acknowledge they have read your comments, it would mean other forum members or readers could just ignore this topic.
