I just got +24 rep for "serial voting corrected" What the heck does that mean?

@DonThousand Someone cast too many votes on you at a time, or vice versa.

So if I got +24, that means someone downvoted me 12 times???

Wow that's interesting

Yup.

@JoséCarlosSantos @Saad @RRL @YuiToCheng @XanderHenderson: Can you believe that this PSQ has gotten 4 reopen votes?

@user21820 I'm not so surprised after seeing the review history.

One more close-vote.

@user21820 The OP provided the Mathematica answer. Does this count as context?

@YuiToCheng No, because it's lazy and anyone can do that. The how-to-ask page spells out what is counted as context.

@user21820 Thanks for clarification. By the way, I noticed this question is asked 5 month ago. Do we apply the 'lack of context' closing reasons to all existing posts? For example, this looks like a well-received old PSQ.

@YuiToCheng If it were up to me, I would apply the guidelines uniformly, since the "research effort" criterion had been built into the system from the start (hover your mouse over the downvote button). However, the consensus currently seems to be to focus on new questions to prevent new poor questions from flooding the site.

I would prefer if moderators historical-lock old poor questions (which they have done before in some cases) since that is the intended usage of the historical-lock, but often they decline or ignore such requests. You could try asking them. Perhaps if more users are in favour of consistency in handling poor questions, they would be happier to oblige. =)

My "old" means something like ">5 years old", but more pertinently one also shouldn't be allowed to take advantage of locking, or in general claim "it's old" as an excuse to preserve bad questions (unless there are incredibly good answers).

@XanderHenderson As pointed out in comments there, the question (right from the first version) wasn't about getting the answer, but why the asker's method still got the right answer despite double-counting some things. Unfortunately, the only answer addressing that real question is in the first two comments. What do you think?

@user21820 This PSQ has been reopened.

Some people are driven by rep-farming.

@quid: Why does it seem that people fight to keep PSQs like this? There's nothing even really valuable here; either use symmetry or count carefully, and the asker could easily have done the latter (but didn't because of course Math SE is well-known for giving full answers to PSQs). Does the pretty picture really make the thread valuable? (I'm not sarcastic here, I do think it's pretty but squandered on a poor question.)

@user21820 I don't know either, but at least it's not the same thing we saw so so many times already.

@quid Haha.. so now what? Shouldn't that PSQ be closed anyway? (Reopening such PSQs is really sending both lazy askers and rep-farmers the wrong signal.)

@user21820 yes, I'd say so. But I don't think it's at the point where I want to get involved. Maybe later.

@quid Alright, thanks for responding anyway!
