Helping people with computers... one answer at a time.
Twitter is fairly new and currently very popular communications tool. Along with popularity comes abuse in the form of spammers.
I included my email address in a 'tweet' on Twitter, and someone told me I shouldn't. Why?
I made that question up, because I noticed today that masses of people are doing exactly that: including their email addresses within posts they make on Twitter.
You really, really, really don't want to do that.
The reason is an old answer: spam.
Twitter in many ways defies description. It's been called a "micro blogging" site, a "community IM" tool, and a bunch of other things. The bottom line is that you post messages of up to 140 characters, and anyone following you can read them.
You'll note I'm on Twitter, and currently include my three most recent posts, colloquially called "tweets", on the right side of my pages. (Feel free to follow my tweets, just visit http://LeoOnTwitter.com.)
So, why is tweeting your email address such a bad, bad idea?
Because anyone can see it. Your tweets, including what are called "@"-replies, are visible to everyone. That's actually kind of the point of Twitter, when you think about it.
Unfortunately, that includes ... you guessed it ... spammers.
Here's a fun exercise to try: go to http://search.twitter.com and search for "hotmail". What you'll get is a list of recently posted tweets that include the word hotmail. And most all of them will be as part of an email address.
Now, imagine you're a spammer looking for valid, known-good, legitimate email addresses to either spam, or spoof. What an incredible resource! A small piece of software to automatically scan and collect all the email addresses that appear on twitter, and the spammer's collecting gold.
So don't let your email address be one of them. At least obfuscate it. Your tweets are likely intended to be read by real people, right? So if your email address is firstname.lastname@example.org make it something like:
me at example.com
or something along those lines.
But don't tweet your bare-naked email address.
Unless you want more spam, that is.
