annotate gpp/forums/views/spam.py @ 348:d1b11096595b

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix #168; when nailing a spammer, clear their profile text fields. Guard against topics and forums that don't exist when deleting posts in the signal handler. Make the forum stats template tag only display the latest active users.
