Strange, I have iCloud instead of Gmail, but I'm also receiving a humongous amount of spam recently too, and while (so far) it goes to the "Junk", it's still a bother when I check daily for missed messages.

Before I would get about 3 or 4 "Junk" messages per week, tops. Now it's more like 20-30 per day.

I wonder if spammers figured out some new method of not being blocked.

EDIT: Someone else is getting the same emails I am: https://news.ycombinator.com/item?id=34898655
