The kinds of questions you mention are good news for me, as an overburdened smalltime sysadmin.

* It's great to get this kind of insight into what my users may try to do.
* Posted answers give me additional insight by pointing me toward vulnerabilities and workarounds I need to double-check and/or close up.

It can't be said often enough.  **Security through obscurity is garbage.**  If we think our networks are secure because our users are too stupid to cause damage, we're in for a world of hurt.  Censorship (even self-censorship) is not the answer.

I like to think there's a reason this issue isn't addressed in the SF rules or FAQ.  Can of worms, if nothing else.

Scenario: if one person decides a question is malicious in intent, and he feels he's responsible for keeping the information in that helpful answer out of our cracker's hands, how far would/should he go to remedy that problem?  Delete answers?  That's 12 kinds of terrible to my way of thinking.
