Do you use "less traditional" platforms for advertising or as a marketing channel?

A few days ago, I read a Pinterest report stating that more and more people are searching for topics related to digital detox on the platform.

I realised that I have never used this one platform as a marketing channel, there is a huge target audience from the US, and it has around 480 million monthly active users – so possibly good for the digital detox app I collaborate with.

Another client wanted to promote on Tinder (tho I wasn't very convinced with such a suggestion as it was not related to the product so much). 😅

What "less common" platforms do you use for promoting the product, and what results do you have?

(I mean other platforms besides Meta products, LI, Twitter, YouTube/Google and TikTok)

Bonus points if you can give any insights on Pinterest promotion. :)
