Multiple accounts notification

So yesterday I also got a notification that multiple accounts had been detected. So, last year I had a Remotask account which I never worked on a task with and abandoned it completely until last month when I created an account with outlier which I have worked some few tasks with. What should I do? It’s telling me that my account is on hold and that I should login with my original account. Somebody help? Is there a way out? Maybe deleting an account?
