I always wonder how it is people receive or see all these scams. Nothing ever appears in my Inbox, no scam calls on the mobile, no scam texts and we only answer the landline if the number is recognised. There's one forum I visit occasionally which displays banner ads based on recent Google searches but that's it.
Other than using a password manager I do nothing special. I can only imagine people leave traces of their activity when on the web.
Sometimes you get onto a list for no apparent reason
then at some point in the future you start getting calls - there is often n you start getting callso connection that you can see because there are gaps in the timeline
sometimes they seem to just create lists of random numbers that may or may not be phone numbers and a call system rings them and analyses the result for sale later
hence you could get a phone call tomorrow - don't answer but the ring tone is enough to confirm it is real
then some time later it rings again and you answer - but they hang up
so - that number is now more valuable
then it goes on a list on teh dark net (or something) - maybe a year ;ater it gets sold - them after a while
