This is a new set of guidelines from Instagram to tighten the spam on their platform. Please note the following limits:
- The total length of the comment cannot exceed 300 characters.
- The comment cannot contain more than 4 hashtags.
- The comment cannot contain more than 1 URL.
- The comment cannot consist of all capital letters.
Starting from version 2.1, Retro will let you know if you have exceeded one of those limits.
