So you are saying I can't opt out of both? Or will they take XYZ_nomap_optout ?

The Microsoft page says it has to contain _optout, not that it has to end with it.

Presumably for this reason; so XYZ_optout_nomap works. But this is just silly.

Imagine SSIDs in a couple of years...

COMCAST56B4_nomap_output_security_reinforce_superhappy_wifienable_security_ALLOW-P^[A-Za-z0-9\.]+$-_DISALLOW-P^[pet][0-9]$

Probably the former.

So it's becoming the robots.txt of routers?

Why do they do this instead of just ignoring networks with hidden SSIDs?

I believe they also ignore hidden SSIDs, but those come with other problems, so they added a way to opt-out without hiding it.

are you saying that SSIDs should have infinite lengths?

sorry if you don't have a sense of humor as this was clearly not a serious question
