Until reducing multiple stubs becomes a bannible offence, I will continue to do it, based on my editorial discression. you have been warned.
You may want to consider the fact that it takes more time and effort to add stubs than it does to remove them.
Personally, I see stubs as being like throwing out a lifeline to some relevant community that you don't even know yet. It's like saying, "Hey, I created this short article about an Australian rock star/politician, for god's sake can someone who knows about Australian rock stars or Australian politicians come along and clean it up!" Removing the politician half, for example, would reduce significantly the number of people who might find it and fix it.
IMHO, stubs are vulnerable because they have so few links to them or from them, and are so likely to get "lost". More links increases the chances that some kind person will stumble upon it and fix it. I never actively seek out stubs to work on - but if I hit one, I occasionally flesh it out a bit.
