Description

tvn24.pl has "premium", magazine and konkret24 (factcheck) sections. the premium thing is not a paywall, but login-required pages, and the account is free to use, does not even require confirming the e-mail address.

note that they almost always include more than 1 video inside the text.

example "premium" content: https://tvn24.pl/premium/grzegorz-wierzchowski-lodzki-kurator-oswiaty-mowil-o-wirusie-lgbt-za-co-mogl-stracic-prace-4673299
does not work at all, even for the video showed without logging in:
