A silly question if I may?

About 15 years ago, I cam across a site which also had a few pages for helping writers. One of the pages was a list of volunteers who are willing to proof read stories - they mostly would specify what kind of fiction they enjoy. Plus they would specify the number of hours they are willing to dedicate per week.

Most of them were either professors or students of Literature, while a few were people whose job was writing text for the advertising industry.

Do such people still exist?
