It is a non-issue. Unless your country doesn't regulate data-sharing, doesn't require personal information be protected, doesn't require breaches to be reported, and doesn't have real punishments in place for people who do. For example, I have gotten recruiter email spam to an email I used/gave to a company for HR communication only (luckily, it was a unique email address). Maybe a spam filter catches most of it, maybe not. It's a losing proposition to need throw-away information and spam filters for all types of information though. No filter is 100% accurate.
