I noticed that in the last few hours (or half a day), 4 of my posts were down voted (3 regular, 1 meta).
It made me wonder if it was done on purpose.
Not that I don't accept being down voted, it means I should check again the question to be sure it's good - but right now it just seems weird.
From my experience, it's odd to get so many (relatively) down votes in such a short period, and without a single comment explaining it. Moreover, two of the questions are around 2 month old, and got positive feedback until that moment, and so again - no explanation about the reason.
The relevant posts: 1, 2, 3, 4.
So is it just coincidence or it was done on purpose?
