@amWhy: Thanks.

The structure, wording and timing of these two questions seems quite suspicious to me: 1, 2

@RRL I missed your big list again (was away). However, your PSQ has been closed and is up for deletion already.
@an4s Those are not the only two! There was an earlier exact copy.

[ SmokeDetector | MS ] Bad ip for hostname in answer, potentially problematic ns configuration in answer (98): limit inferior and superior for sets vs real numbers by Rajiv Banga on math.SE

[ SmokeDetector | MS ] Bad ip for hostname in answer, potentially problematic ns configuration in answer, blacklisted user (169): What is the limit inferior and limit superior of sequence,$x_n=\left(1-\dfrac{1}{n}\right)\sin \left(\dfrac{n\pi}{3}\right),n\geq1$? by Rajiv Banga on math.SE

Can I no more see in a question whether I close-voted/down-voted it ? This would be annoying since the message "you have already down-/close-voted" would occur quite often. Hope this is a temporary problem and not one of those "great and necessary" changes like in the layout of the site.

@Peter Open for deletion – and perhaps this as well.

This question about the integral test looks like a duplicate to me. I am hesitant to wield the golden hammer, therefore I left only a comment. There may be even better duplicate targets.
