A social network is having many filters that can trigger flags or bans for accounts. Here is how to safely change accounts profile data without hitting those filters:
It starts with the usernames and names. When editing account usernames and names, avoid spammy and repetitive keywords.
When uploading avatars or feed photos, avoid using the same images between multiple accounts. Use Batch Purifier to remove hidden image metadata. Also, use different file names for the images.
When adding biography or photo captions avoid using flagged keywords like hack, crack, cheat, giveaway, free followers, free iPhone… and any adult-related keywords. Be creative and don’t use the exact same text between accounts. Use a spinner (combined with some manual edit) so you’ll have different text for every account.
PLEASE NOTE! As of early 2019 Instagram made an update that can affect accounts having any profile data updated via a bot API. Instead, you can use a normal browser with the proper privacy addons; or use the bot embedded browser for updating profile data.
