Instagram deleted numerous accounts without notice or warning after account holders attended the Friday, October 16th, 2015 Janet Jackson concert at the Forum in Los Angeles, CA and posted video clips to their Instagram accounts.  Instagram accounts should be given notice and/or warning to take down any pictures or videos that do not comply with Instagram's terms and conditions before Instagram completely deletes the account. The weird thing is that you can then go on and start a new account but lose all of the precious pictures from over the years. What is the point of Instagram if losing pictures from important life experiences are deleted for ever? Instagram needs to review its business practices and change there ways or they will loose customers that they have had for years. This is disappointing that you can't have trust in your account members to give them fair warning/notice and then if not followed you delete. Please let me know how we can resolve this problem immediately. Possible announcement at concerts, events, etc... is a good way to warn attendees of events like they do at theater gatherings.
