[OpenFontLibrary] Recent non-font content on OFLB

[Daniel Johnson]

I've noticed a number of non-font uploads (and some outright spam)
posted on OFLB recently.  I haven't done an exhaustive search, but the
following uploads are not fonts.  The first is spam, and the other
three are just images.

Is there a plan in place to ensure that every OFLB entry has a font attached?

Cheers,
