Any Other Ppc Freelancers/tiny Agencies Getting Relentless Spam About "investor Interest"?

I manage Google Ads accounts for a small list of clients as a freelancer. At one time I was a Google Partner, but I've been moving away from search marketing to pursue other things, so I'm not putting much effort into expanding my PPC work. I tend not to get many real inquiries from clients or anyone else. My website is clearly way out of date (still says AdWords I think).

Over the past year or so, I've been getting spam from people who claim to be connected to family offices or institutional investors who are eager (to the point of sending multiple messages per day or even hour sometimes) to acquire my PPC business or obtain an equity stake. It's clearly some kind of scam and likely using AI sales tools to attempt to include relevant details.

While this is probably just a function of AI, what's caught my attention about it is the relentlessness, which seems remarkable even by spam standards (blowing the standard spam we all probably receive about white label services, web developers, and getting my website to the top of Google out of the water). They've even started to email me at my other business, which is in education, not marketing (referencing my PPC website, so it's not just that every business email address they can find is getting the same spam).

I'm not very concerned about this and I've been able to deal with the problem all right with spam filters. I don't interact with the messages, and when I open them to improve the spam filter, I do so with images off to avoid an open being recorded. Occasionally one slips through to my main inbox, but I usually only notice them when I glance into my spam folder for false positives. (More than anything, I'm concerned that despite the messages consistently going to spam over a long period and being easy for me to spot, Fastmail still gives them a fairly low spam rating. Email providers seem like they have a lot of work to do to adapt to the nature of spam in 2026.)

Just wondering if anyone else has the same experience. If I had a ton more free time and a more adventurous spirit, I might try to mess with them to satisfy my curiosity, but I'm going to settle for just asking if anyone else has noticed this. (Though long shot request: if anyone has any tips for removing myself from sales databases so I can get less spam like this, I'm all ears. Probably not possible, I know.)
