What we will censor, is when you start calling the person who sold you the thing names.
Racial epithets, general slander kind of stuff. You will have to support your story with some kind of credible evidence that you didn't just go break it. You can't just come here and say " don't buy from so and so, they suck", and then not support that statement in some way.
Or, we might get rid of your spew if you change your story enough for us to tell that you are not honest about your problems.
But if you have a legit gripe, gripe away, and please, do tell us who sold you a bad product. We do need to know who has good CS, and who doesn't. We also need to know who won't put up with a customer from hell, just in case we should become one some time.
So tell us your story, and let each reader decide which it is, vendor from hell, or customer from hell.
