Frankly, if you treat effortful but green contributors the same way you treat grindset morons and LinkedIn jockeys, I would put money on the submission rate from the latter continuing to increase long after most of the former have decided your project isn't worth their time.

This is a bit of a moot point, though, since I don't think it's very common for Linux kernel maintainers to behave this way. Correct me if I'm wrong.
