like I said before, even if you don't have something smart to say, if you post something bad

That is anti-social behavior. Another way to put what you are doing is "posting deliberately provocative messages online": that is definitially trolling. (Unfortunately, your form of trolling, because it is just provocative rather than offensive, probably doesn't meet the standards for reaping trolls).

Intentionally posting bad advice in response to other questions or intentionally posting bad code without asking for help to annoy people into correcting you is rude. And it's dangerous, because someone might actually follow your bad advice, without understanding the risks of what your code might do to to someone who uses it.

Please stop this anti-social, bad-for-everyone behavior.
