There are Instagram comment problems where you cannot comment on popular Instagram accounts with a newer account or you cannot tag multiple users in the same comment.
This is all due to Instagram cracking down on spammers. If your profile looks like a spammer based on your profile picture or bio link and you are constantly tagging people or only commenting on popular accounts you may run into comment problems.
You cannot leave a comment that includes;
- More than 5 @ mentions
- More than 30 hashtags
- That is the same comment multiple times (even emoji)
If you have an error commenting on Instagram, remove a few hashtags or @ mentions.
