[this is a tweet]<p>[@zippergz this is a tweet]<p>[this is a tweet for @zippergz]<p>I have no idea if these are different.  I know my followers get to see the first example.  But do they get to see the others?<p>I have no idea what happens if I post these as a reply to a tweet that you posted.  Do I <i>need</i> to keep the @ handle in there? Or is it being a reply sufficient to trigger an alert on your end?<p>I just now got followed by a porn account.  So, I&#x27;m not interested in the porn they produce, and I&#x27;m never going to tweet to them.  Either they&#x27;re spammers who are just following everyone, or they&#x27;ve seen some sex industry relevant tweets I&#x27;ve retweeted (because another person I followed researches the sex industry) and thought I&#x27;m worth following. I have no way of knowing. So do I block them? Or just ignore them?
