Alert boxes are bad design

I associate them with XSS these days.

I went to another old image board with ancient software that is still around (but just barely), and seemingly-randomly had an alert box on the page that said ``wut'' and I thought ``oh shit, this site is owned'' but I did some research and found out it's not XSS, it's a feature!

https://github.com/Laurelai/tsukiboards/blob/master/lib/javascript/kusaba.js.bak

onFailure: function ()
{
alert('wut')
}

The world's least helpful error message.

It's clearly some undergrad's toy project, let it go. It's also a .bak file, not real js.
