Bot attack on challenge

A bot attacked a challenge and sent 70+ complaints to this entry and the next.http://www.dpreview.com/challenges/Entry.aspx?ID=664351&View=Results&Rows=4

I thought dpr would have seen this by now, without me having to raise it in the forum.

It also pops up a dialog box, supposedly to ask the password.

PS:  I hate the new interface to type a message.  It is so iPad unfriendly, I hope the developer gets what he deserves.
