Yes I've definitely noticed a rise. Each email always mentions something about me that gives away where they scraped my email from. Some of the sources I've gotten spam from: github (most common), academia.edu, HN who's hiring, Show HN I don't get annoyed at emails like this because I accept that if I'm posting my email along with my work in a public place, I am inviting people to email me about it. Emails are easy to ignore, so I don't get annoyed at receiving emails like this. Even if these services are automated, at least they're semi targeted, and maybe 1/10 might interest me. One time someone emailed me promoting a business with an interesting business model and I replied and spent some time discussing it with him. What does annoy me is that they get through my very strict gmail filters. I filter every email to an "ignore" label unless it's directly addressed to me and not categorized by gmail as "primary" (i.e., not one of social/promotions/updates/forums). It works very well and basically zero newsletters get into my primary inbox. But these emails are different. It seems these emails are categorized by gmail as "primary" which means they escape my filter. I wonder if, ironically, gmail filters newsletters by looking for an unsubscribe link. Because as you mentioned, I have noticed that none of these emails have an opt-out link.
