What a week Twitter is having.

First came word that New York Times editor Jon Weisman was giving up on the network, because of its failure to stem the tide of anti-Semitism being tweeted in his direction. So, while Twitter has promised to better police bullies and bigots, Weisman’s departure shows that such efforts have been insufficient.

Then new data emerged showing that ad agencies are increasingly bypassing Twitter for other social networks -- Instagram especially. That might explain why the company recently slashed its second-quarter revenue guidance to $590 million from $610 million -- nowhere near analyst expectations of $678 million.

Then(!), eMarketer released a new forecast suggesting that Snapchat will overtake Twitter in terms of domestic users, before the end of the year.

Now, Twitter is notifying millions of its users that their accounts are at risk of being hijacked.

“The purported Twitter @names and passwords may have been amassed from combining information from other recent breaches, malware on victim machines that are stealing passwords for all sites, or a combination of both,” Michael Coates, trust & information security officer at Twitter, explains in a new post.

“We’re confident the information was not obtained from a hack of Twitter’s servers,” according to Coates.

Such assurances are likely cold comfort for users, many of whom may already have concerns about digital security and privacy.

Will this latest incident inspire users to follow Weisman’s lead and move to another social platform? (Weisman said he was moving to Facebook.) Maybe not. Yet the continued rise of rival networks, along with unfettered bullying and additional security gaffes, can’t bode well for Twitter’s future.
