Here's a solution. Everybody creates their own (free) Mega account.

Then add [email protected]

as a contact.

Create one folder in your Mega account and share that with [email protected]

Now the [email protected]

account will have all videos of everybody, but they can't be deleted anymore.

I've just shared the videos that I had imported from the [email protected]

account, you can find those under "contacts" at mega.co.nz

usr: [email protected]

psw: hwas

Hope this works.
