Neither myself and the mrs use jarvee but we noticed we were both following a page that neither of us manually followed - “sportsdirectfootball”.
It’s not a page that just changed it’s handle that we don’t recognise.
Engagement is extremely low in some cases, generally less than 0.5% - they have 1.9 mil followers now.
Are they paying instagram for unwilling followers or what has happened?
Are you sure it’s not an account you followed long time ago? You can go to that account’s profile on IG app, click on the message button, IG will show since when you have followed the account.
For the low engagement, you may need to analyze your account and see what you are doing wrong, or check with an IG expert to find out the issue and improve your engagement.
