Here is a copy paste what i got today from my host:

Code:

I have noticed that spam emails were originated the through the script /wp-admin/profile.php. Please delete the offended files from your account. Also, you can only send e-mails to those who have requested it. Your mailing list must be an opt-in list, you also need an opt-out option for any removal requests, and you will need to honor those requests in a timely fashion.

 If you have any further questions, please update the Support Console.

What is here wrong with my wp? How to solve this? I have about 15 wp sites hosted on this provider and they asking me now to delete some key files from my wp.

Did you approve comments?
Because approving comments sends the commenter an email and mass emailing counts as spam on some hosts.
