To get things back on topic...
What do the models think about the people that might cap for their own personal use? IE that they never intend to share the caps with anyone. Are these people a large percentage of cappers? Probably not. But, I'm sure they exist. But, then again, I also assume that the actual percentage of cappers on the sites is fairly small compared to the total number of members. Anyone who has ever found caps of a model online will probably notice they're normally a bunch of the same caps probably just shared with multiple people who go and repost them on different places (and you can pretty easily find caps of any model by using Google and their model name).
So, would models care as much about those cappers that never distribute, but just want to save shows for their own use later? Although, I would assume, much like the private archives on MFC, without the interaction, such caps would be less interesting than when they happened.
Obviously, most of the models on here don't care about screenshots of them in certain threads, even though they are distributed for all registered users of the site. The silly cap thread, dat ass, socks, tummy love, etc. Many models seem to not care when funny emote GIFs are made of them from things that happen on MFC... A lot of other sites don't allow the uploading of custom emotes, so easiest to mention MFC here. But, obviously, funny GIFs were capped somehow, either by separate still screenshots or as a movie file that was then turned into a GIF.
I'm sure that each model would have different views of these, though. Some might not want to be capped, ever, while others might not care about caps to make funny GIFs or screenshots or for the (probably rare) personal use cappers. Even for distributed caps, we see varying degrees of acceptance. Some see it as potential advertising, even if they're not happy with it. Some see them as the next coming of Lucifer, a bane on their existence and that they should be burned in the fiery pits of hell. Some decide based on what the distributed cap is... teasing/just nudity being ok, but actual cum shows being a problem.
Even so, like I said, the percentage of people capping is probably lower than it is made out to be when one sees the amount of capped shows. The problem of distributed caps, I think, comes from the amount of places the caps are posted and the amount of people willing to redistribute said caps, even if they didn't cap them themselves. From my own experience capping video game footage using screen capping programs (multiple ones to try and get a quality I needed), I know that capping video takes up a TON of hard drive space, especially with sound, for the raw files. Even using my EyeTV and my HDPVR, my raw files are huge. I have close to 40 GB of game footage to edit and export to smaller file sizes, right now... and the MP4 files exported are roughly the same size for the quality I need for my reviews (before I edit them into the reviews, obviously). And I don't think as many people out there have as much hard drive space, total, that I do (over 3 TB between internal and external hard drives) to be recording as many shows as possible. Plus the time it takes to export from screen cap programs... trust me, recording an hour of video can take at least as long, sometimes longer, to export (depending on the program and computer).
The effort, hard drive space and time required to cap shows probably turns a lot of people off to capping, period. Oh, and also the potential cost. At least on the Mac side, worthwhile screen cap programs run anywhere from $25 to over $100. Even on Windows, the free screen cap programs tend to record in shit quality, so a good screen cap program is going to cost money. I don't even want to imagine the cost of the setup the site originally mentioned in this thread must have cost. And if the idea behind capping public shows is to save time and money, I would tend to think the time and money needed to do it to the degree people seem to do it would be too much for the people searching for the free shows in the first place.
