As for the site....it's preferable to restrict yourself to sites where YOU are in control of your works.....where you have the capacity to upload, and delete again if needed, and not be at the mercy of the site's admin.
Your own property should remain under your direct control.
There 'may' come a time when you wish to remove works and 'if' there is a potential for your wishes to not be followed then the system is less than ideal...
