Over the past week, several of you have reported receiving spam emails. Upon investigation, I discovered a common factor among all the reported cases – email addresses being publicly displayed on web pages. This highlights the potential risk of displaying email addresses online and emphasizes the need for adopting more secure communication methods to avoid such spam and phishing attacks.
This subject is covered in the Cyber Security Tool Kit which I hope you have read:

Displaying email addresses on web pages can lead to several issues, including:
- Spam: When email addresses are publicly displayed on websites, they can be easily harvested by spammers and added to mailing lists, leading to an increase in unsolicited and potentially harmful emails.
- Phishing: Email addresses can also be used by hackers to conduct phishing attacks, where they send emails disguised as legitimate ones to extract personal information or spread malware.
- Privacy: Displaying email addresses can also compromise the privacy of the email owner. This is especially true if the email address belongs to an individual rather than a business.
- Email overload: When email addresses are displayed on a website, it can lead to an influx of emails from people with various inquiries or solicitations, which can be overwhelming to manage.
To minimize these risks, I strongly recommend using the contact forms I have provided on your websites, which will help avoid the direct exposure of email addresses. Additionally, I have incorporated CAPTCHAs on these forms to prevent automated spamming by robots. However, it’s important to note that this measure cannot entirely prevent human beings from filling out the forms with spam messages. Nonetheless, using contact forms and CAPTCHAs can significantly reduce the risk of spam and phishing attacks resulting from publicly displayed email addresses.
