Follow the exciting details in http://thread.gmane.org/gmane.discuss/12234
The only Gmane reading users who will see the (more than half of) Platonides' posts that were marked as spam are the users who use the Gmane NNTP interface. The users of the web Gmane interface won't see them, as per http://gmane.org/spam.php .
And for us Gmane NNTP users who trusted Gmane's judgement on what was spam, and put things into their noffle.conf etc. NNTP clients' configuration files like filter group=gmane.spam.detected action=discard well, now we must do e.g., $ wget -O - http://lists.wikimedia.org/pipermail/wikitech-l/2009-April.txt.gz | grepmail -h Platonides|grepmail -h jidanni for every month, for every mailing list, to find all the valuable replies we missed.
