The biggest surprise to me with all this low-quality contribution spam is how little shame people apparently have. I have a handful of open source contributions. All of them are for small-ish projects and the complexity of my contributions are in the same ball-park as what I work on day-to-day. And even though I am relatively confident in my competency as a developer, these contributions are probably the most thoroughly tested and reviewed pieces of code I have ever written. I just really, really don't want to bother someone with low quality "help" who graciously offers their time to work on open source stuff.
Other people apparently don't have this feeling at all. Maybe I shouldn't have been surprised by this, but I've definitely been caught off guard by it.
