Received request for folder access

[Dan N 1]

I found an email that indicates somebody requested access to an Evernote folder of mine. The folder is currently private.  It's not clear to me how someone even knows I have that folder. So, it's a two part question:

1. Do I have a security concern, or does Evernote allow people to ask for a folder to be shared with them?

2. If Evernote does allow someone to ask, how do I turn off visibility to my folder names?

No one should have access or a view of your EN notebooks and account.  Did you sign up for some third party service that works with EN?  If not, I would send the info to EN in a support request.
