Facebook / Instagram app name review

Hi Everyone,

I would like to start developing my new app idea, which uses Graph API, but I just found out that before I can switch my app to Live Mode I must complete the App Review process.

There is all kind of restrictions, I guess, all of them are just fine except one.
It says:

• Your app is using Facebook's Company Brand in a way that is not permitted
• be named in a way that may be confused for Facebook or any of our subsidiaries (for example, app names such ash “FB Friend Smash”, “FVideo”, or “Friend Smash - Best FB Game” will all be rejected)

The problem is, my app name and domain name uses keyword gram as a suffix, here is an example: lologram.

Do you think guys, is it a valid reason to reject my app?

Thanks a lot
