I have compiled some statistics for the three moslty used hosts. The data is taken from my forum-backup.
The data is not absolutely correct, so take it with a grain of salt. For Example the post date is not necessarily the date of the image upload. Forum-backup does not parse post update dates yet. The posts are mostly taken from Magazine and Classic Pornstars sections.
Usage of image hosts (number of images) per year (post date)
Image download success rate for posts by year (post date)
Image download success rate for posts in 2017 (post date)
Success rate of the second download if the first download failed:
imagebam.com 3.61% |
imagevenue.com 9.69% |
imgbox.com 2.40% |
What I have observed is that image download fails are often clustered. There are posts with dozens of images where most of the images have failed an posts where all images succeeded.
