I'd like to see forced legislation requiring marketers to disclose the exact source and campaign they acquired your data in.
I've been getting a barage of non-stop harassment via unwanted magazine subscriptions. People Inc claims some company called "Subco" signed me up and won't allow me to cancel, only "Subco" can do that. "Subco" then claims they got my information from someone else down the line. They then blame someone else, someone else...
... and I still have no clue who the hell decided to sign me up for 20 magazines in the mail.
Yup. Someone clearly scraped my LinkedIn and sold the info as a bogus lead, I've been getting several texts/day about business financing, and the occasional call. Ironically, the calls were better--every caller understood they had bad data and never tried again.
