Instaspy will scrape posts from a target account, check previously archived posts against the online account at time of download, and output a text file listing any previously archived posts that the target has deleted.
$ pip3 install instaloader
$ python3 instaspy.py [TARGET]
or set as cronjob. TARGET is the username of the profile you want to archive. The list of deletions is stored as {TARGET}deletionhistory.txt.
