Practical Steps to Block Spam and Take Back Your Privacy
Are You Part of the 460,000 Daily Spam Reports?
According to the government's official spam report for the second half of 2025, spam reports and detections totalled 23.67 million — roughly 130,000 a day, and 39% fewer than the previous half-year — so while the tide is finally turning, digital noise still drains our time and focus. Ever wonder how strangers get your name? It usually starts with an innocent-looking checkbox labeled ‘Agree to Marketing Use’ or ‘Agree to Third-Party Sharing.’ Those hasty clicks during sign-ups are often the backdoors through which your personal data leaks.
How to Effectively Silence the Spam
The best defense is cutting off marketing channels at the source. Here is how you can leverage official tools to clean up your digital inbox.
- Register with Do Not Call: Use the ‘Do Not Call Registry’ managed by the Fair Trade Commission. This allows you to opt out of telemarketing calls from major sectors like finance, insurance, and telecommunications in one go.
- Use 080 Opt-Out Numbers: If you receive a promotional text, the 080 number at the bottom is toll-free. Under telecommunications laws, the sender is legally obligated to stop contacting you once you request an opt-out. Use it.
- Direct Withdrawal: If a specific company won't stop, contact their customer support directly and demand they revoke your ‘Marketing Consent.’ It’s the most definitive way to stop the cycle.
Is Your Data Already Out There?
If you suspect your information has been compromised, it’s time to track your digital footprint. Check out the ‘My Leaked Info Search’ service provided by KISA. It allows you to see if your email or user ID appeared in past data breaches. If you find a match, change your passwords immediately and turn on 2FA (Two-Factor Authentication) for added security.
The Golden Rule for New Sign-ups
Stop clicking 'Agree to All' when creating new accounts. Always expand the options and only check the ones strictly necessary for the service. Be especially wary of prize giveaways—these are often data-harvesting traps. Ask yourself: is that discount code really worth exposing your phone number to a dozen third-party marketers?
What to Do When the Spam Persists
If you've already opted out and they’re still calling, they are likely breaking the law. File a formal complaint via the KISA Illegal Spam Response Center. Don't just hit 'Block'—reporting these numbers helps curb illegal marketing chains for everyone else.
