Twitter is a publicly traded company and one of their metrics is tweets per day. Spam is in their best interest. Same goes for snapchat. It's a bit twisted but when snapchat or Twitter can say "X million photos/messages per day," who cares if it's all spam? Who's gonna prove them wrong?

Especially when those sort of numbers might be used to justify the price of advertising on the platform.

That said, I wouldn't say that it's in their BEST interest– too much spam and real users start getting turned off. So spam up-to-a-point.
