No, what is the consequence, how has quality of Twitter diminished? As a “normal” user I can not observe any degradation of Twitter service.
Most common thing people use it for is posting and reading. If you fake feeds as if they are real-time then the viewer will never know there was a system outage.
I am almost positive there was a massive security breach too.
That's a very serious allegation, as it would be illegal to not report it. Can you add some details?
