One of my [answers][1] to [this question][2] got deleted by community.
Now, as I understand it, community handles automatic tasks, and so this might have not been done by an admin. Now, it isn't about the rep, but If there's something obviously wrong with this answer, I'd like to know what, so I can avoid pitfalls that would result in an invalid answer. As far as I see it, there's nothing *obviously* wrong with the answer.

I'm not sure if its related to [this][3] but its possible
