We’re not able to comment on individual and specific cases here on the forums for privacy reasons. If an app is suspended you should have received an email notification explaining why this occurred, and providing follow-on actions and a response mechanism. This would have been sent to the email address associated with the owner of the application account.
The other recourse is to use our Platform Support forms which direct through to the team that works on policy and application access.
That said, the below notes are high level thoughts on what might have gone on, but you’d need to check any email notification or contact the team via the forms to confirm whether any of these things apply.
Aggressive following might be indicated by large numbers of follow or unfollow requests being generated / an app repeatedly hitting those API endpoints within an unusually short period of time. We want to avoid scenarios where bulk follows or unfollows can occur, as these have been found to be signs of “spammy” apps.
Additionally, our Botmaker technology automatically watches for potential bad uses of the platform, and an app that (for example) repeatedly Tweets out similar phrases, suspicious URLs, or uses a lot of @mentions, might be temporarily muzzled while the issue is investigated.
I hope that helps a little!
