Here is a thing I can't understand. We recently got a question from a new user. That user has only account at Programmers.
Their question has a piece of text that appears to be copied from markdown help at Stack Overflow:
Use italics and bold together if you have to.
They couldn't copy it from Programmers because our markdown help has different wording:
You can combine them if you really have to.
It looks like user attempted to ask at SO before dropping their stuff at us.
I logged out and tested how it is for an unregistered user to attempt asking at SO. System just didn't let me through to Ask Question page, it required login before getting in there.
How could this user get to Ask Question page at Stack Overflow (and copy text from that page) without having an account there?
