How Not To Use Social Media

A contestant in a beauty contest while soliciting for votes from her Facebook friends posted a link to the website where her friends could vote for her on her Facebook wall and in the alternative also asked them to send to her their email addresses and phone numbers so that she could use them(email addresses and phone numbers) to do the voting in case they couldn't do it themselves.  Some of her Facebook friends in responding to her requests posted their email addresses and phone numbers on her Facebook wall. Below is a screenshot of the relevant portion of her Facebook wall:

Phishing and Spam
Some of her friends decided to post their email addresses and phone numbers on her Facebook wall, instead of sending same to her Facebook inbox. This is not good as the addresses and numbers posted on her wall can be viewed by person in any corner of the world who views her Facebook wall as it appears that her Facebook privacy settings does not limit the persons that can view her wall. Therefore, what those friends did is akin to walking on the streets of every country in the world and giving anybody they come across including strangers their email addresses and phone numbers! Probably those her friends who posted their email addresses and phone numbers on her wall thought that it is only her and her Facebook friends that could view their chat which contained the email addresses and phone numbers or  it could be that they knew all that but did not give a damn! Well, they should give a damn. Why? It is because scammers could use their email addresses and phone numbers to defraud them through a technique referred to as phishing. Phishing refers to the process of deceiving recipients of text messages and more often, emails into sharing sensitive information with an unknown third party (usually a cyber-criminal).

Typically in a phishing email scam, you receive an email that appears to come from reputable organizations, such as: banks, social media (Facebook, Twitter), etc. Phishing emails may be indiscriminate. A phisher will create an email asking the user to get in touch with a bank or credit card company claiming that there is a problem with the account or that the bank may have lost some money. These sorts of messages make people justifiably worried and more likely to follow the instruction. The phisher will then include some plausible looking details such as the bank’s logo and address and then send it to millions of individuals. Among all the recipients, a few people will have accounts with that bank and will click the link in the message, or telephone a number, which will begin the process of eliciting further personal information such as account number, ATM PIN and password, internet banking login username and password which he could use to hack into or log in into a bank account and steal money.

There are times when we receive unsolicited text messages or emails from people or organizations we do not know (spammers) and then we wonder how they got our phone number or email address. Posting your phone number and email address on your friend’s Facebook wall is one of the ways they could get your phone number and email address and then start sending you spam or spam messages. Spam simply put is irrelevant or unsolicited messages sent over the internet typically to large numbers of users, for the purposes of advertising, phishing, spreading malware (computer viruses) etc. These messages could be annoying and can include bogus offers that could cost you time and money.

Conclusion
In order to avoid been scammed through phishing or spam messages or to not receive spam  messages try to limit how you share your phone number and email address in public and online (blog posts, in chat rooms and on social media networking sites). Spammers and scammers use the web to harvest email addresses. For more internet safety tips and how you can use social networking sites with minimum risks click here and here and here.
