I use the following method about how to bypass iCloud activation screen lock.
Go to "Wi-Fi Settings" > tap the "i" symbol next to the WiFi network to which I want to connect > Remove the existing DNS > Input the new DNS according to my location
Below are some DNS and a relevant article for reference.
For users in USA/North America, the new DNS is 104.154.51.7
In general, to remove the iCloud activation lock, it is easiest and quickest to contact the previous user. But if you are buying from eBay and the seller has no way to provide you with an Apple ID, try to remove iCloud activation lock without password.
