Definitely one of the most annoying issues on the Internet: long, unreadable privacy policies.
No one takes the time to read them, assuming carelessly that their privacy is protected. Still, the data is rarely safe from misuses. For example, your email address might be leaked to spammers by a misbehaving/lazy service providers. One technique to defend against such service providers consists in watermarking your emails. Assuming that you have a gmail account,
- Use the following format when giving out your email address: username+serviceID@gmail.com where serviceID is the name of your service provider. Gmail will correctly forward the email to you.
- Check your spam folder looking for watermarks!
