I'll note that both of those forum links are from 8 years ago and may not entirely reflect current practice. Their "Sources" page also notes their own crawler the DuckDuckBot, and references connections with more specialized searches like Yelp and Stack Overflow. Just to give a bit of context, that forum discussion was 8 months before Snapchat was founded and 6 months before Google bought Motorola Mobility (which split off just before the thread in question).
