Yes, I am familiar with libraries and considered building an app on the back of whatsapp until the DMCA takedowns. The fact that whatsapp is fighting against bots is part of the reason there is so little spam on whatsapp. Yes, people do crazy thing with accounts, and in many parts of the world there are good reasons to have multiple SIMs. People will have 1 IG for sexy photos and another for their family, etc. But there is far less motivation to do that with whatsapp, line, viber, kik, etc. The reason for the difference in motivation is that your whatsapp messages are explicitly shared with individuals rather than with groups so there is no need to partition messages by accounts. The main reason for have two whatsapp accounts is the old joke about having two SIM cards: "one for your wife, and one for your girlfriend".
