Why Email Spam Looks Better Than Usual These Days

The problem with making coding easier for more people is that it makes spam more conventionally attractive. Which is bad.

Tedium: The Dull Side of the Internet.
Blacklisting Phone numbers and IP are gonna become extreme now, to the point it wont allow any unknown number/email without `karma` to reach anyone.

I don't understand why something like this exists natively on phones.

If someone calls from an unknown number, they get some sort of captcha to prove that they are a human, or they matter is important.

For example, the message should say that, if you are geniune, then please call again after 1 minute..

That already exists, it's "voicemail". The scammers never leave a voice mail (idk why). If a real person is trying to reach you, they'll either leave a voice mail or text you after you don't pick up.
Many spammers leave a prerecorded voicemail, they call quickly from 2 numbers so they can slide into your voicemail instantly without ringing more than once
