Have you tried different throttles? Did you get any whatsapp account(s) banned at higher speed?

[aleixrodriala]

Yes, used different messages max sizes, with 2000 characters got the best speed but got the account banned, using 20000 is a great middle term and not banned for now, could get banned anyway, its an educational project

Could you try encoding data as images for better bandwidth (and probably worse latency)?

[allanrbo]

Images are often blocked on the free WhatsApp on airplanes

[cyclotron3k]

I wonder how that's implemented if all the traffic is encrypted. Presumably images are sent via a different domain or IP address?

[projektfu]

During the Facebook outage of a few years ago, WhatsApp messages still worked but I couldn't send an image. I think images are uploaded to Facebook-related servers and messages are through a separate real-time infrastructure, and it's likely that the message includes the fuzzy thumbnail and a url for the image from the other server.

Message size, perhaps.

And volume.

[tambourine_man]

Perhaps the client knows it’s on a free internet tire and blocks anything other than text.

Much easier to implement than encrypted package inspection.

Using less characters got you banned? I don't understand why that would happen. I would think using more characters would be more likely to get you banned since it's less like what normal users do.

[mkagenius]

Its in the README - it increases the the number of messages.

[Thorrez]

Well increasing the usage would also increase the number of messages.

How does Whatsapp choose to ban people? Total messages sent? Then increasing the message size doesn't stop you from being banned, it just makes it take longer before you're banned. Messages/second? Then avoiding the ban by a message size restriction seems like a very clumsy way of doing it; it would be much more straightforward to avoid the ban by limiting the messages/second.
