The livestream portal is installed in New York and in Dublin. Brendan McDermid/ReutersThe Dublin-New York video portal has shut down again as it's tech fails to stop inappropriate behaviour.It was meant to bring people together in joy, but ended up bringing out the worst in people.Here are some other examples of fun but ultimately ill-fated tech projects.A livestream video portal aimed at bringing people together across Dublin and New York went viral this week for all the wrong reasons.What started out as a touching display of cross-Atlantic connection — people could wave at those 3,000 miles away and unite with long-distanced loved ones — soon devolved into chaos.People were seen flashing their naked body parts, holding up pornographic videos to the screen, and showing photos mocking 9/11.The inappropriate behavior prompted Dublin City Council to close the portal overnight on Monday.
