Pretty sure it's a different problem - alert() is a true modal dialog that blocks almost all other normal interactions and is very disruptive. Back in the day when apps weren't constantly gaming all user interactions to squeeze on extra ad click out or whatever, it was still abused - but rarely.

Now if you wander down the wrong internet 'alley' you'll get mugged by someone using alert() to almost completely hijack your normal session. Especially for older folks (my grandpa really suffered from this), it becomes impossible - to the point they'll even call someone up and give them their credit card number sometimes so they can 'get to their email'.

Warnings to the dev console won't stop this type of harassment of users - only stopping it from being the modal dialog it is supposed to be (per alert() prior behavior) will.

Every major web browser has implemented a "do not show alerts from this site anymore" checkbox that appears after 2-3 consecutive alerts.

"Protecting the users" is an absolute lie.
