This Page says regarding Vimeo basic accounts (i.e. free accounts):
We consider accounts that have not been used for a full year to be
inactive, and we reserve the right to remove inactive accounts.
Does Vimeo actually delete accounts that have not been used for a full year?
Best Answer
Yes, as already stated in the link, Vimeo deletes accounts and all uploaded videos for accounts classified as "Inactive". There is no way to gain those vidoes back. This is a common practice followed by many free hosting sites and servers.
