They probably rotate accounts, but still, those "I need a financial advisor / SamSpam worked for me, telegram->" comment clusters feel like they've been the dominant form of spam for years but shouldn't have taken years to target with a model. It's even worse on eBay, where there is a spammer who has used the same set of fake pictures and listings for at least 5 years now. I call them the "Comic Sans Scammer" for reasons you can probably guess and they still drop junk into my feeds like clockwork every weekend. Ugh. I'm sure I don't see all the fronts of these battles, but with the size of the companies in question it feels like I should be seeing more back-and-forth in the fronts that are visible to me.
