A user created a thread to voice their bad experience with ubuntu.
http://ubuntuforums.org/showpost.php...postcount=6116
1) Telling users what to do (the user didn't ask for help).
2) Calling his opinions "complaints".
3) Implying that his opinion was unwanted.
This is all underhanded insults, of course, which is what ayusi does. He/she doesn't call people names directly, he/she just creates a strawman of what they say and insults that straw man. (In this case, a person's opinion on why they don't like ubuntu becomes a "complaint", for example).
