Will internet archive (Archive.org) delete my content if I upload some copyright protected files (music) ?
They say they will but I can find almost any new and top rated song on the site with high amount of views but they didn't delete them.
Note: Don't worry about my own security; I'm in a third world country out of reach of US government hand.
Please don't, they have DMCA issues for ages because people try that but they are legally required to take that content down if they receive a request!
They will delete it if they get a DMCA takedown request, as required to avoid liability under US law. They don't however proactively look for copywriten content. As long as the music owner doesn't care or doesn't notice it will be fine.
Why not use something else? I know what community this is but still. Internet Archive serves a lot of important purposes and they've got enough heat on their back as is.
I've had material taken down after years of sitting there with thousands of downloads. On the other hand, I have material that has been there just about as long with similar download counts, and it hasn't been touched. It all depends on if it gets flagged or not.
