As I have explained to ladies again and again, no good ever comes from posting full face photos or allowing anyone in the hobby to have same.
Absolutely nothing ever posted on the Internet can be fully removed. I know of more than a dozen archival sites (Google being the largest and most active) where "supposedly" photo removal requests will be considered, but rarely have I seen anything be totally disappeared.
Just consider Tineye, for example. Last time I looked (this morning as a matter of fact) here's what Tineye told me:
"Searched over 3.6623 billion images in 1.094 seconds."
Now, although Tineye is promoted as a "reverse image" search engine, my hunch is that its business plan sooner or later will include forward searching as well. And not just by face, but by potential or possible web link or web site.
With many dozens of archival web crawlers operating, who is to know where or even how to find whether your face (or other image) has been crawled, stored, and gawd knows when it will pop up somewhere down the line.
Not to scare, horrify or pair-a-noid anyone, but millions of faces have also been collected by multiple law enforcement agencies from the feds to the states and cities. Damn near unavoidable if you enter public spaces, such as airports, bus terminals, even shopping malls.
And, yes, ladies, be on the alert for gents who take your pictures when you visit their premise or when they "innocently" prop their cell phone on your dresser with the camera pointed toward you or the bed. No sh*t! Heard about another one of those jerks just last week!
But, in these internet spaces, most of us have full control over our faces and whether someone captures them or not.
