According to the help center, new users with less than 10 reputation can't post more than 2 links:

New users cannot:

• post more than two hyperlinks at a time, either in a post or their user profile

I always thought that this applied to all links, until I came across this answer. The answer in question was posted by a user with 1 reputation and had, before I edited it, 3 links: 2 to screenshots on imgur and one to a Stack Overflow question.

I thought that seemed strange so I decided to test it with a 1 reputation sock puppet. I tried the following markdown code, which contains the 3 links from the answer:

I didn't get any error message for this code. I also tried to replace stackoverflow.com with superuser.com and meta.stackexchange.com and it still worked. But when I tried to replace it with something that's not Stack Exchange, for example example.com, I got the error message "You need at least 10 reputation to post more than 2 links". I also tried to replace it with a Stack Exchange site that doesn't exist, for example oiqewjr.stackexchange.com, and I got the error message.

So it seems like new users aren't allowed to post more than 2 links to non-Stack Exchange sites but they're allowed to post as many links as they want to Stack Exchange sites. But I can't find anything in the help center that says so.

So what links count for the 2 link limit for 2 users? Only links to Stack Exchange sites? Why is this? And can the help center be made more clear about this?
