What is the best way to organize file storage on third-party resources?

Question

Data storage

Good afternoon
I would like to give people on the site the opportunity to upload files - video, photo, audio. But I don't want to mess around with storage, backups, etc. I thought about creating communities in the social. networks, youtube, etc. and send everything there via the API.
Has anyone encountered pitfalls? What can go wrong? Let's say he noticed that VK sometimes loses pictures, and it can close the ability to show files on other sites.
Is there anything like youtube but for pictures/photos and audio?
You can also paid services with a good API
Thank you

If you don't care about copyright issues, you can, otherwise most of the content will be eaten up by checks (youtube is merciless, it can pass with VK).
For images there is imgur , for audio - hardly (DMCA is a merciless thing).
