I don't know how much Flickr is used these days, but I remember it was quite popular some 15 years ago. I decided to search around, and discovered that it is a treasure trove of photos from the period 2005 - 2015, and incredibly easy to search / filter.
Internet archeology is something I've always found fascinating, and I don't think people realize how much data has been lost after we moved to the modern "big tech" internet of today. So many data hosting services disappear back in the mid/late 00s, and with that, the data too. After social media exploded, many just stared storing all their photos there.
