The cost of uploading a PDF of links is probably not much less than the cost of following those links on your own. So I don't think you gain much by leveraging Facebook in this case.

Perhaps Facebook starts opening every link using 10,000 parallel threads. Can you really replicate that from your connection at home? Perhaps even the sysadmin of your victim site has whitelisted all Facebook IP addresses so their crawlers get a free ride.
- gojomo 7y agoThere's a fair chance the service which generates these outbound requests throttles itself, both with respect to how many requests it makes against any one domain/IP, or how many errors it will provoke per time period, or before human review.
- zeptoon 7y agoMaybe, maybe not
- zeptoon 7y agoIt's this kind of thinking that unearths the bugs
- GhostVII 7y agoI would imagine it queries sequentially so it wouldn't have too many parallel threads. Not much reason to parallelize.
