Twitter, which announced the move on its blog on Thursday, illustrated the upgrade with this Aug. 11 tweet from astronaut Chris Hadfield:

“As you can see from @CMDR_Hatfield’s Tweet embedded above, we’ve put the photo front and center, with a bigger and bold visual focus on the media,” Brian Ellin, Twitter’s project manager, platform, wrote in the blog post. “Both landscape and portrait photos now have more room to show their pixels when the Tweets are embedded online.”

Improving the photo experience make them more viable for inclusion in articles now that there’s competition from Facebook. Facebook’s embeds came as the company was revving up its real-time marketing opportunities (shortly before, the company introduced hashtags). Instagram, a unit of Facebook, launched embedded posts in July, shortly before Facebook did the same. Instagram’s embeds include video as well as photos. Twitter’s Vine videos are also embeddable.

For a short period, Facebook had not only caught up with Twitter, but also surpassed it by letting news organizations run richer embeds in their stories. Now, the two appear to be on equal footing.

In addition to the texts and notifications, ‘alert’ tweets will appear alongside an orange bell icon in the Twitter stream.

“Twitter Alerts [is] a new feature that brings us one step closer to helping users get important and accurate information from credible organizations during emergencies, natural disasters or moments when other communications services aren’t accessible,” explained Gaby Peña, a product manager at Twitter, on the company’s blog.

Twitter already has more than 70 participants for the new system, including The American Red Cross, FEMA, and global non-profits like the World Health Organization. In addition to state and regional accounts (like the New Jersey State Police), Twitter Alerts also partners with a number of international accounts, mostly in Japan.

Users can specify which accounts they’d like to receive alerts from at their setup page: twitter.com/[username]/alerts.

Twitter has already solidified itself as a valuable communication tool during times of crisis. Following events like the Boston Marathon Bombings and Superstorm Sandy last October, Twitter was used by media organizations and authorities to share news quickly and to those without cable or landline access.

This new feature comes on the heels of another alert feature Twitter announced yesterday. Twitter’s mobile users can now receive follow recommendations via push notifications, too. Users will be alerted when a number of people in their network follow a new user, or retweet or favorite the same tweet.

What’s notable is that these spammers weren’t sending tweets or direct messages. Instead, they made use of Twitter’s list function, adding people to various lists and indirectly pointing thousands of users toward spam sites.

Lists are typically used to organize Twitter users into more distinct groups. You might have separate lists for celebrities, colleagues and friends, which allows you to monitor several different streams at the same time through tools like TweetDeck. A few months back, Twitter increased the number of lists each user can have from 20 to 1,000 and the maximum number of accounts in each list from 500 to 5,000.

While not entirely new, as noted by BuzzFeed’s Charlie Warzel, it’s a capability that is now being abused by spammers, who are adding users to lists populated with links en masse. Each time you’re added to a list, you get a notification on Twitter and perhaps via email. Naturally, you’ll be keen to find out why you were added to the list and, spammers hope, click their links.

One of the biggest offenders in the current wave was an account called Celeb Phone Numbers. Before Twitter suspended it, the account automatically added tens of thousands of users to lists. It promised to reveal the phone numbers of stars like One Direction singer Tomlinson and Lady Gaga through an associated website.

Warzel reported the person behind the Celeb Phone Numbers account used a Twitter keyword marketing tool to find people who had tweeted about those stars and added them to its lists. That person shared their finding on marketing forums, spurring other spammers to try the tactic. The spammers make money if you complete surveys or view ads on their sites.

The Celeb Phone Numbers account was immediately reported as spam by many users Sunday night:

Twitter is fighting a war against spammers. A study published last month showed how vendors created thousands of phony accounts and sold them to spammers wholesale. Twitter is adding the researchers’ methods for finding such accounts into its abuse-detection systems. Tracking down and killing spam accounts is a high priority as the company prepares to hold an initial public stock offering.
