Question FTP users can still delete files they don't have permissions for?

[awfy4]

It used to be that I could add some files to a users subscription into their domain's httpdocs folder with the ownership set to root:root and it would prevent them from editing or deleting it but still give them access to execute/read the file. Seems that's no longer the case and hasn't seemed to be for a while.

It seems that any FTP user for a subscription can delete any file regardless of ownership or permission.

Is there a way to revert this functionality or some other way to restrict access to prevent FTP users from deleting or editing files?

Thanks

And what are the permissions exactly on the files?

I've tried permissions of 000, 400 and 600 all with the same result.
