Summary: The above is important because of the timing. After 5+ years of pension fraud at Sirius 'Open Source' the company enrolled staff without paperwork/signatures and barely with any consent (in late 2016); to make matters worse, a few years ago it upped staff contribution levels without increasing its own, in effect forcing staff to send even more money (one's own money, not the company's) into this dubious pot with uncertain future.
So far we've been spared (our network has not been targeted at all) [...] Let's hope the spam won't discourage the hundreds of thousands of people worldwide who still use IRC
