Probably not, it used Chat-API [0], but the developer is kind of an asshole. But I admit, people just post stupid issues all the time. However I don't share the developers opinion that this was abused. My friends and I haven't received spam messages on Whatsapp. I admit that may be a small sample size, but still.
I did the same about mid 2015 using yowsup (Python API to Whatsapp). But it's was a private project because of legality concerns of hoarding so much data.
