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

Then add dondihair@gmail.com

as a contact.

Create one folder in your Mega account and share that with dondihair@gmail.com

Now the dondihair@gmail.com

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 dondihair@gmail.com

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

usr: dondihair@gmail.com

psw: hwas

Hope this works.
