My own timeline was compromised, so I started looking into this. A fake tweet was posted on my behalf with "Twitter for iPhone" as the source. I don't have an iPhone since quite some time, but I used to have the app back in the day and never revoked access until now.
Luckily my timeline was not affected.<p>However, I wonder, shouldn't Twitter be able to pick these messages up automatically fairly fast, after (I assume) hundreds if not thousands of users have flagged them?<p>Also, the spammers can't have unlimited IP's. Twitters anti spam kinda seems to lag back behind E-Mail (subjectively).<p>Is there a reason the same techniques used in E-Mail aren't applicable to Twitter?
