I heard from one poster that his account was closed, but he had about 200 or 300 files mostly from one site which get reported again and again and so maybe the site owners **** the pressure to rs. But's thats the only case i "heard" of and it's been a while since.
I have now about 10 files a week blocked by rs. So i'm trying to keep an eye on my uploads, means that i check them with rs-linkchecker to see if any files are blocked (put your links in a excel-file to manage them). It might be a bit naive but i like to believe that if i delete my files by myself (after being blocked) before rs deletes them, they won't mind
But as said above, rs depends on porn-uploaders, so i think you and i have nothing to fear.
