I haven't tried out FullBlogPlugin with SpamFilterPlugin 0.7 or greater yet, but you will be affected by the issue I experienced tonight while trying to patch the DiscussionPlugin in #8764. There is a simple change needed to account for a class having been moved:
try: #SpamFilter < 0.7
from tracspamfilter.api import FilterSystem
except ImportError: #SpamFilter 0.7+
from tracspamfilter.filtersystem import FilterSystem
I implemented this for the DiscussionPlugin in . I wanted to bring this up now in case we might use SpamFilterPlugin 0.7 and the latest FullBlogPlugin with the trac-hacks site upgrade.
