Stop cybercrime.
Protect mental health.

Every scam that lands is a mental health event. Blocktober trains everyday people to close the gap technology can't — by talking to the humans around them.

Become a Blocker
AUD $3.1B lost to scams in Australia each year
1 in 3 victims report lasting anxiety or depression
10 blocks the goal for every Blocker

Why this matters

AUD $2.2B lost

Australians lost to scams and phishing in 2021 alone. Elderly, youth, lonely and disabled people are hit hardest.

Trauma is real

Victims experience panic, depression, and a phenomenon we call digital disability — too afraid to use technology after being burned.

People fix what tech can't

AI and ML detect threats. But only human conversation stops a parent from clicking a phishing link. Human connection is the missing layer.

The Power of 10

If every Blocker prevents 10 attacks for the people closest to them, a community of 100 becomes a force that stops 1,000 cyber crimes.

Not corporate awareness campaigns. Not government alerts. Just people — talking to their dad about a scam, warning their colleague about a phishing email, checking in on a friend who almost got played.

It's small, it's personal, and it scales.

How to be a Blocker

01

Sign up as a Blocker

Register and get your own Blocker page. This is where you post updates and track the attacks you've helped stop.

02

Bring people together

Catch up over coffee, food, a picnic, a BBQ. Use that time to talk about scams you've seen, security habits worth building, and what to watch out for.

03

Count your Blocks

Log every conversation, every warning shared, every person helped. In person. On social media. Anywhere. Every block counts.

October is Cyber Security Awareness Month. That's when Blocktober peaks. But the work runs all year.

The principles behind Blocktober

01

Human first, tech second

Technology detects threats. Human relationships prevent them. We invest in people, not just tools.

02

Small actions, real compound

One conversation with one person about one scam sounds small. Multiply it by a community and it becomes a defensive network.

03

Digital resilience is mental health

We refuse to separate cybersecurity from mental wellbeing. Exposure to fraud is a primary cause of anxiety and depression. We treat both.

04

Community owns the mission

Blocktober isn't a company telling people what to do. It's a community of people protecting each other by choice.

Join as a Blocker

Blocktober needs people, not experts. If you can have a conversation, you can stop a crime.

  • Report scams to the people around you
  • Support victims — don't just send a link
  • Educate your circle before they get hit

No spam. We'll only email you about Blocktober updates.

"A Life of Virtue is the philosophy that inspired Blocktober's founders to start this movement with the purpose of bringing people together — starting with our closest family and friends."

By practicing eudaimonia — giving your most precious time and attention to raising awareness on cybersecurity and mental health — you become part of something larger than yourself.
