Ask HN: Has Gmail spam blocking taken a sudden nosedive?

I woke up this morning to find five obviously spam emails in my Gmail inbox. In the preceding decade of using Gmail, I don't believe even a single one has made it past the spam filter, so I'm quite curious what could be causing the sudden influx. These aren't some cleverly crafted ones either, subject lines include:

𝐘𝐨𝐮𝐫'𝐥𝐨𝐚𝐧-𝐢𝐧𝐯𝐢𝐭𝐚𝐭𝐢𝐨𝐧_for_up to$𝟓𝟎,𝟎𝟎𝟎'. (sent from [email protected])
