I'm a long-term Rocky Horror Picture Show cast member, and I run a web site for our local cast in Austin. I've been running this web site for over a decade now.
Cast members are frequently very interested to see photographs of themselves performing in the show. And since it's Rocky Horror, they're usually wearing lingerie of some sort. At the time the photos are posted, they're invariably very excited about this. Especially because I take pride in my photography, and most people haven't seen photos of themselves prior to this that someone had actually put significant work into.
A few years later though, these same people have frequently quit the cast, possibly graduated from college, and moved on to other activities. They may decide they want to apply for jobs in education, as music minister of a church, etc. They do some vanity searching on Google and are shocked... shocked I tell you!... that the Rocky Horror cast web site is still online and kicking with what had been posted some years previously.
Now keep in mind this is a hobby web site that I do purely for the enjoyment of myself and other cast members. It's done in my spare time, and I've always paid for it out of pocket.
I'm sure I could honor requests to remove all of these photos, but I simply don't want to. It involves a lot of time and effort on my end, to accomplish something that's actively taking away from things I take pride in myself. I get probably a half dozen requests per year on average at this point all basically saying the same thing: "Take down my photos now! You're causing damage to my reputation!". At some point I just had to say to hell with them all and whip up a form letter response saying "Sorry, but I'm just not going to do anything about it".
