It’s not quite a bug, but nor is the reason completely obvious.
There are two questions at play here:
Why didn't Snape keep or secure his copy of Advanced Potion-Making? (asked yesterday)
Why did the Half Blood Prince leave his book in the Potions dungeon? (asked 30 Apr 2014)
Originally I closed the new question as a dupe of the older question. But the ...
The user you're referring to is currently suspended. He earned the gold Socratic badge before his suspension, at which point he had many thousands of rep, but his rep is set to 1 for the duration of his suspension. You can still see on his profile that he has posted a great many questions.
This is by design.
From the main meta FAQ How do comment @replies work?:
Note that the author of the post will always be notified of any new comment. You may still use it for clarity, if needed; however if only you and the author have commented on the post so far, the @name will be automatically removed from the beginning of the comment, as it adds no ...
The base amount of flags per day is ten but you get more per day as a reward for having more reputation or good flagging history - up to 100 total flags per day.
If you read the flagging privilege page a bit more closely you'll see it says all the way down at the bottom:
How many flags do I have?
When you start out, you are allotted 10 flags per ...
The reputation from upvotes is capped at 200. However, some things aren't capped, namely:
Points from accepted answers (+15 if someone selects your answer)
I see in your case someone selected your answer, thus you got a bonus 15 points. So you could actually get 10 more points still.
Deleted candidates is not a scenario well-supported nor one we have any intention of encouraging.
I manually patched up the list of winners, which should be sufficient to indicate what happened. But we will not modify votes or alter any other data connected to the election (that is: We're not going to create fake users with fake votes winning fake ...
We don't create meta profiles for users until they actually go to meta. So, if you've never visited, you'll not have a link to the profile, since it doesn't exist!
Once you visit (assuming you're logged in), it should always be there.
Similar question was asked previously on our main meta site.
It’s because it’s (basically) locked
You can’t edit the post because it has been merged, yes. Thus the remaining stub post has been locked.
As detailed here, hovering over a locked post on meta will produce precisely that error. Similarly here. As mentioned in the comments on the first post, it seems that the system interprets any edit made under less-...
That's called spoilertagging.
People use it to mark content that could be seen as spoilers. E.g. in the answer you link to, people who haven't seen The Force Awakens might not want to mouse over those sections of the text and learn what happens in the film.
See also the various spoilers posts on meta, e.g. How should I be indicating a question is, by its ...
It sure looks like it's serial vote reversal, since it happened to me twice.
The first time I voted was in the evening of Jan 1 (so it would have already been early on 2 Jan in UTC) and a few hours later those votes were gone. I voted again on the Q and some of the As but now early on 3 Jan (again, in UTC) most of those votes are gone again.
I've asked ...
Yes, the contents of both sidebars are cached. Looking at the current code, the Linked sidebar is cached for 5 minutes, and the Related sidebar is cached for 1 hour.
The entire HTML content of the sidebar is what's cached, not the question IDs or what not. So the scores for the questions won't be updated live.
To add to Pearson's excellent theoretical answer, you can see specifically where you got the rep in 2 ways:
Your reputation tab on user page:
Note the green square around the last line's rep (15) - that "+15 accept" is what caused you to get 205. Green background indicates that ...
I think you're talking about the "How to Edit" / "How to Format" boxes in the right sidebar which appear when you're asking or editing a question. If I've misinerpreted your question, I'll delete this answer.
This is by design, and isn't going to be changed.
The same issue has been raised on main meta: Right-hand sidebar covers the footer on the "ask ...
