It's not Karma. It's the fact that your comments are persistent. On 4chan, they have a life between a few minutes and a few days, and that it really. No persistent ID to lay "claim" to your work. It's not about whether someone else can identify you by your comments, its about the psychology of creating something that will exists for an indefinite time, that your peers will read and judge, and thus judge you. You feel the same feeling even when contributing to 4chan, however, you know it wont matter for long thus it's far less mental weight to deal with.
