AFAIK a user is allowed to ask questions only once in 20 minutes, but this user asked two questions in just five minutes.
The questions are
Differences between restricted repositories and partner repositories?
What are the differences between "precise" and "precise-updates" and "precise-backports"?
Was this because he has 3k+ rep, or because of his tags, or a bug?
The rate limits are all explained in this meta post on the main meta. I am reproducing the relevant part here:
Asking
- Users < 125 rep, 20 minutes (90 minutes on Stack Overflow)
- Users limited by Anti-Recidivism System, one question per week
- Users < 10k rep trip Captcha if more than once per 60 seconds
- Users > 10k rep trip Captcha if more than once per 30 seconds
- On Stack Overflow, Super User, Server Fault and Math (not active on all other sites)
- maximum of 6 questions per day
- maximum of 50 questions per 30 days
As you can see, there is no limit for users of >125 rep, they only thing that happens is that they trip a captcha request if they ask more than once per minute.
There is no limit at 5 minutes. In fact, for most sites, there is no limit on the number of questions that can be asked at all.
2014-07-11 07:54:28and the other at2014-07-11 07:59:52. Thus in fact, it's more than 5 minutes. It's 5 minutes and 24 seconds. What is the restriction? One question per 5 minutes?
