accounts = email spaming database

Alienfaucet admin proved it.
Of course! When you register on websites like faucets or other "no name" websites, are you using your main eamil?
If yes, treat it as a lesson:
Don't do that anymore! Create new email address that you can treat as an "emergency" (something like spam folder)
You're welcome

You no need to teach me, try to bring it to the majority part of faucet users

About bots : for registration and validate email's accounts with similar to the real people do not need to have a high skill in C# or C++. However, registration will repel the average user who uses faucets and faucet owners gonna lose their traffic.
