I recently sold a day spa in Silicon Valley that I operated for 30 years; I've also concluded 20 years of spa management consulting and am ready for a new industry (even though I'm shocked to discover that landlording does not include free facial treatments and pedicures.) 

In the background they do facial recognition.

Applicants with body odder, unkempt appearance, attitude, messy car, facial tattoos any reason you may have.

Damn you people who can control every tick of your facial muscles!

Home inspectors: I know some with a solid understanding of construction having owned properties en masse and then I’ve met the ones who show up with peach fuzz for facial hair barely having left their moms spare bedroom writing reports with 300 things they flag, killing a deal due to their incompetent opinion. 

Online, the context, facial expressions, delivery and tone of messages delivered can easily be confused or come across wrong.

If he has not yet filed his intended claim of adverse possession, then your title to the property is facially sufficient for you to assume exclusive use of the property and I agree with @Lynnette E.

These are good and the newer versions/models had facial recognition that snap shots zoomed in faces and sends those faces to your phone which is better than a screen shot of the entire screen because you'll end of going to viewing footage on other notifications (something is at side gate). 

Can you discriminate against the guy that reeks of smoke and booze or has 15 facial tattoos?

I sent a plumber there immediately, and the reason this time as well was facial tissues in the sewer line that caused the obstruction.
