Update: I originally wrote this post with hopes of being able to provide you with the link to check if your information had been breeched, but I, like everyone else cannot provide a link.
I find it extremely frustrating when bloggers and companies write posts about these hacks but provide you with zero sort of help. I wont waste more of your time, but I finally found out that the list was only accessible if you paid to view it. However, a user made the list publicly available which is why there's an uproar from planet Earth. I'm not sure why other sites wont tell you this, I guess they just like the clickbait effect.
As a developer I'll see if someone posts something within the development community, but until then please be sure to go to Facebook and do a checkup on your privacy using the links below. Or you can delete everything Facebook knows about you; but keep in mind that you will no longer have a Facebook account, so if you care about your personal photos, and contacts/friends then you might want to simply deactivate your account so that you can download your data at another time, and then delete the account.
Here and the button below are links to Facebook which is a list that can tell you if you are part of the hack that started in 2019 but was reported upon in April of 2021.
