Yahoo yesterday announced a huge spike in quarterly profit but was red-faced over a performance by lap dancers at a Taiwan developers’ event...

However, the online ad giant has been forced into an apology for inviting lap dancers to its annual Taiwan “Hack Day” last weekend.

Photos and videos of the short-skirted “Hack Girls” appeared online early this week, prompting angry responses from developers and bloggers.

Chris Yeh, the head of the developers’ network, said he acknowledged that the Hack Girls were “not reflective of [the] spirit or purpose” of the event.

But posters to his blog pointed out that the dancers had been invited to the previous year’s developers’ event.
