How to unlock an iCloud locked iPhone 5s?

I found an iPhone 5s a while back and it is stuck on this and I want to know if there's any way to unlock it and how?

ICloud Lock is an anti-theft feature, this means it is impossible to bypass. With recent stories of Apple vs FBI, you can tell how serious Apple is about security. There's no way of bypassing an iCloud lock, and person/site saying otherwise is 100% scamming you

You should return it since it is useless to you & no there's no way around it.

There are ways to get past the lock but it will be quite expensive and there's no certainty.
