Final answer:
Individuals can masquerade as others through unauthorized access to email accounts, email spoofing, and lack of proper netiquette. Care must be taken when composing emails to convey the intended message clearly and to prevent identity theft or reputational harm.
Step-by-step explanation:
Someone might masquerade as someone else using email or Instant Messaging through various deceptive practices. Firstly, by gaining unauthorized access to another person's email account, an imposter can send email appearing to be from the legitimate owner. This might involve guessing or phishing for passwords, or using malware to take control of the account. Secondly, email spoofing can be used, which is when the sender's address is forged, making the email appear to come from someone other than the actual source. While modern email systems have measures like SPF, DKIM, and DMARC to detect and prevent spoofing, not all systems are fully protected.
Email etiquette, or netiquette, places emphasis on understanding your audience and being cautious about how your message may be perceived. It's recommended to compose your email carefully, ensuring it conveys the appropriate message and considering the possibility of your message being forwarded or seen by unintended recipients. This is especially important to avoid scams and protect against identity theft. Impersonation can harm reputations and relationships, especially if the true identity of the sender is discovered.
Moreover, it's advised to handle sensitive conversations in person or over the phone if an email would exceed 200 words, as lengthy emails can lead to misunderstandings or be insufficient for serious matters. When you use your name in your email address, it also serves to authenticate your identity and can prevent confusion or impersonation. Email communication can be a powerful tool for positive online impressions if used with consideration and respect for netiquette.
