With the launch of Pokemon GO there's a huge number of automation bots going around, requesting for user's Email and Password. So my word of advice is practice safety precaution and be aware of all the official bots as well as the newer ones as It doesn't take much effort for a developer with malicious intent to change the source code into stealing your account information.
Do patiently wait for people to review the bots first before trying it if you have no experience in reviewing the source code, Thank you.
