Discord [1] is taking a toll from the increased traffic as well:
"We're noticing an elevated level of usage for the time of day and are currently monitoring the performance of our systems. We do not anticipate this resulting in any impact to the service.
We have temporarily disabled typing notifications. We expect these to be re-enabled soon."
Have gotten multiple such emails the last couple of weeks.
I think Googles spam detection is a bit too much lax when the sender itself is using gmail.
These might as well be hacked accounts which have already proven themselves to be valid and "human" at a previous point in time? I doubt gmails spam detection would let a brand new account spam CC'd emails without any sort of detection.
