A single layer of deflate compression has a theoretical expansion limit of 1032:1. ZIP bombs with higher ratios only achieve it by nesting a ZIP file inside of another ZIP file and expecting the decompressor to be recursive.
This means you can serve 1M payload and have it come out to 1G at decompression time. Not a bad compression ratio, but it doesn't seem like enough to break Facebook servers without taking on considerable load of your own.
