Instagram blocks my posting due to suspicious activity

The Instagram Security Service detects that you are trying to post from another service and blocks the publishing of these posts.

If you post to Instagram with their official app, these restrictions will be lifted over time, as the Instagram Security Service will be sure that you are a real person posting to the Instagram account and not a bot—and then you can successfully post to Instagram using POSTOPLAN.

Also, in order to remove restrictions as soon as possible, we recommend that you do more activity from the official Instagram app: click on the Like button, subscribe to other accounts, and publish your stories.
