I can’t prove it, but it feels like the world recently decided that spamming/scamming is acceptable, so the number of spammers/scammers has increased dramatically.
The number of spam calls, texts, emails, iCloud account unlock requests, etc I’ve received in the last year is insane.
It's AI that's doing a lot of it. For a lot of spam, scammers would want to exclude anyone who may not fall for the scam due to the costs associated with dealing with people who won't pay you. Now that AI decreases the need for a human scammer to scam, expect them to start to widen their scam nets.
I think part of it is AI allowing sophistication at scale, but there's also a generational factor. The techbro + business shark culture, influencers who manipulate people being role models, and so on.
I believe that these spammers now concentrate their efforts towards e-mail addresses hosted by major providers, like Gmail.
The reason is that I have an opposite experience, during the last couple of years I have received much less spam messages than before.
I have hosted my own e-mail server for more than 2 decades. Previously, I had to filter large quantities of spam messages, but lately the number of spam messages is much less than 10% of the total number of received messages.
