There is no one definitive way to determine if an Instagram account is fake, but some tips may help. First, check to see if the account has been inactive for a significant amount of time. If it has, it may be fake. Additionally, look for any suspicious posts or comments. If they seem too real or if the account seems to be run by someone who is not actually a user of the platform, it may be worth checking out. Finally, make sure to check out the account’s history and see if there have been any changes in ownership or management. If all of these checks turn up negative, then the account may be legitimate and you should continue using it."
