I had this issue before. I was complaining about a product on a forum and was a bit annoyed because it was expensive and did not work properly. I didn't call them names, but it was obvious in my tone that I was dissatisfied. Sadly, the moderators on that forum called it "trolling" and I got banned. Those moderators sadly also made money through the company I complained about since the forum is linked to the store.
...but we're just hoping at this point that they use your definition of "nice" and not the version I gave where having "bad" opinions is "abuse".
