Yep we saw it as well. The blanket message designed to get rid of the accounts that have purchased 10,000 followers for $100 and they are delivered instantly. Buying fakes is just fake and we do not endorse it. Great connections, followers and influencers actually takes a little effort to build.
The main thing is your account is 100% safe with Social Growth Engine. We are constantly in contact with Instagram to ensure we comply with their terms of service and that we adhere to the API Instagram allows us to use.
So in summary, all is ok! You do not need to change your password, just click the X (top right) and keep growing!
