Not necessarily, but quite likely. If you take a close look at the common complaints, you might notice that about 50 percent are of the kind "The problem can be resolved by replacing the user".

Another 30 percent can be grouped in the "does not have the least clue about how the gnutella network works or would be better of if he only would RTFM (respectively RTFW (read the friendly webboard))" category.

Another 10 percent can be wrote of as the common "U use other program than me. Me using most perfectest program. U must be stupid. Me most rulez!" troll.

And the last 10 percent are real decent existing problems that will hopefully be solved in future releases.
