I am often hesitant to offer this kind of correction because I feel like it sometimes sounds conceited, or as if I am trying to be superior to you somehow. I honestly don't feel that way and am just offering the correction because I feel like I would like to be corrected myself. I respect you for having learned a second language, it's more than I can say for myself.
But my witty jokes aside, that reminds me of Little Snitch for Mac OS, which keeps installed programs from opening unauthorized connections to the outside. Is there a firewall setup that works this way for an entire home network? Possibly something that could be run on a small device/router?
I wish I knew a name for a homophonic typo which suggests criticism in that way, I used to know a guy who made typos like that all the time, emails from him had a kind of surreal meta-level quality to them. It is kind of a mondegreen, but not quite.
