I've found during my own research that running an OS X VM sending out iMessages for too long will eventually get itself and its host machine blacklisted from iCloud services for a few days. Not sure how they detect the host but I can cause it consistently. I think the VM is blacklisted by its bad SN

Blacklisting/intentional degradation happens with volume sending on a real mac mini too.

Do you have any documentation of precisely when service starts being cut off?

[throwaway150207]

No, sorry; I stopped using iMessage because it wasn't worthwhile to integrate with a system that didn't approve of my use. But when you get cut off, there's no explicit indication, the messages are just not delivered, I think I stopped getting indications that people were on iMessage (the green? bubbles) as well.

[camhenlin]

Yeah that's what I've come up with in my testing as well. It's kind of surprising that there isn't more research into it. Just all of the sudden iMessages stop sending, then a few days later they magically start sending again

Sounds like your OS is... a POS!

I never actually experienced any rate limiting/blacklisting issues while I ran it. I even tested spamming messages to myself, it worked but upset my iOS notifications a fair bit maybe I just got lucky.
