Freesound Forums

In my collection of sounds from FreeSound, there are few samples, which are now absent on FreeSound itself (probably deletede by their original uploaders). Unfortunately few of those users are now gone, too.

I want to use these sounds giving proper credits/attribution but there is no data available about license chosen by uploader. What I have are original filenames with FreeSound ID and username prepended.

I suggest to implement searching in filenames/IDs/usernames/etc of DELETED files, too.
Such data could be crucial for projects based on deleted sounds.

OR maybe license tags should be added by processing script to filename, for example "1234_someuser_CC0_mysound.wav"
