I was checking the Necrobot page and found this on their github. GitHub - NECROBOTIO/NecroBot: The biggest Pokemon Go Bot in history. Good Bye!
"Due to legal action being started against other bot creators/devs (we did not receive a letter yet) the Project development will be stopped. All Source Files / Downloads will be removed. We now have to say Good Bye to the awesome Community. Over 100k Members on Discord and 500k Downloads a day! The Discord Community will remain open for Discussions. It was fun, we had a nice time. Thank you for the Donaions, all Devs will be getting their share by today."
Is Niantic cracking down on bot creators and suing them?
