In terms of how to approach the user's request, the best course of action is to inform them that providing or sharing torrent links for copyrighted material is both illegal and unethical. Instead, suggest they look for legal alternatives, such as official YouTube channels of the samba schools, streaming services that have the rights to the content, or even contacting the samba schools directly for any available recordings.
It's also important to highlight that many cultural events, including Carnaval, have official media partners who can provide access to videos and photos legally. Encouraging the user to support the creators by accessing content through legal channels respects their rights and the sustainability of such cultural events.
Also, the term "Brasileirinhas" might be part of the title of a specific event, album, or compilation. However, without specific knowledge of a known title by that name, it's hard to confirm. The user might be referring to general Carnaval footage featuring young women from these schools.
