What's this?

Yahoo! Japan sometimes shows a nag screen that advertises PayPay or LINE account coordination upon logging in.

This script detects these nag screen and automatically skips it.
NOTE: This script is aimed at those who don't like PayPay.

Yahoo! Japan was formerly promoting T-Point by showing T-Point Registration Page (T-POINT利用手続き) nag screen, and this script also blocks it.
(T-Point is a Japanese loyalty program managed by Culture Convenience Club, and Yahoo Japan is affiliated with it.)
