Many chat is no longer safe to use my instagram account shadow banned and im no longwr able to send dms to new people

I ran an automation to send links to people, and after about an hour I noticed I could no longer DM new users. It’s now been two days and the issue still hasn’t been resolved.

avoid using ManyChat at all cost unless you want your account to get banned. Why do they not have  fail safe where if you have sent to many messages it stops.
