Hey /u/AJ-Styles,
Our EA Support team will never reach out to you and issue a 'warning/strike violation' like this via a third party platform. If we had any need to contact you, we would do it via your email address that is linked to your EA Account, not via PlayStation messages. I would advise that you report and block anything you feel may be suspicious to let the platform know of it and as always - stay safe online, don't issue out any personal details to anyone.
