Yes there is risk but you can lessen it greatly by masking your Prodinfo (serial number) using exosphere.ini and blocking access to Ninty servers by configuring dns:mitm. Both come with Atmosphere. Here is a link on how to set it up.

Once that is complete, you can test everything is blocked with 90DNS tester.
- 90DNSTester -- DNS tester to make sure Ninty can't find you while playing hide-n-seek!
At that point you can install sys-Ftpd-lite. It’s the one I use because it runs as a Sysmodule at boot up so you don’t have to turn it on/off.
- sys-ftpd-light — minimal resource ftpd server
thank you again for your information with your help I was able to block nintendo dns, check it and run a ftp server on it sucessfully
I'm still not sure if I want to leave the wifi on after leaving it on plane mode for such a long time
