I hope you are going to persuade them to adopt a well-known and clearly
DFSG-free license (such as the GNU GPL v2, which is apparently the base
from which they derived their non-free "YaBB Public License").

I have just read through the license text and I haven't spotted any
further issues, besides the ones you mentioned, except for one:
the license text is clearly derived (in part) from the GNU GPL v2 text.

Creating a modified version of the GPL is permitted [1] by the FSF, but the
preamble has to be dropped (but it was not!) and the
instructions-for-use have to be modified to not mention GNU (but they
were not modified enough!).
Only the requirement to change the license name seems to be complied with.

You're welcome and good luck with your persuading effort!
