Even if someone asks a question that you do not think is worthy to be discussed then simply do not respond. I've been to many forums about (4 or 5 to be exact) and if there are threads started about oil changes on a car forum, people simply just turn the cheek. I am not saying there is no good information here, the reviews are excellent (that's how I found this community), but there is a lot of unhelpful responses that do nothing for the IPO (including this one).
Also, if you can't take what you dish out...then go about it.
