File-hosting services like Google Drive, Mega, MediaFire, and Dropbox are built for legitimate file sharing, but they're sometimes used to distribute pirated content. A single upload link can be posted across forums, Telegram channels, and other sites.
File-hosting abuse is hard to stamp out because uploads can be anonymous, links don't require an account to open, and new links can be created quickly after a removal. On the other hand, established file hosts generally have working abuse and copyright processes and act on valid notices.
Removing the file itself breaks every link that points to it, wherever that link was posted. Pair file removal with Google de-indexing of the pages that share the links, and keep monitoring, because the same files can be uploaded again. Privly includes file hosts in its scanning and takedown work.
