For about a solid week or two, I felt like everywhere I went, someone commented how they “kept getting tons of spam calls” — without knowing that I had been experiencing the same thing. Every 20 minutes, it seemed, I was getting a text from “the courthouse” or a call from a number that my phone detected as potential spam.

I consider myself fairly tech-savvy — perhaps thanks, in part, to being a zillennial — so I can usually identify spam and ignore it. But I have to admit, some of the texts, emails and calls I’ve received more recently seemed somewhat legit.

After further research, I was able to discern what was spam (read: all of it) and ignore the messages. But ever since, and even in the past, I’ve wondered: What’s up with this major uptick in spam calls?
