Removals in Debian are only performed after the submission of a bugreport filed against the (pseudo)-package ftp.debian.org. To make life easier for the ftp-team please use the following format (reportbug ftp.debian.org will guide you through it and automatically follow this format):

The subject of the bug should be of the format
RM: $PACKAGE -- REASON
for a full removal request ($PACKAGE is the source package) or
RM: $PACKAGE [$ARCHLIST] -- REASON
for a partial removal. The arch list should be enclosed in [] and separated by a space. If the removal is meant to be done in a suite other than unstable add the suite to the package name, separated with /.

$REASON should start with one or more of the above listed acronyms, whichever fits best, followed by a short but descriptive text explaining why the package should be removed. That text should be self-contained, ie. one should not need to read the body of the request to see why the removal should be done, as this text will end up in the removal logfile. (But of course the body can and should contain much more details than this short subject)

How to help

If you want to help out, the most helpful thing you can do is to ensure that the bug titles follow the above defined format.
You can also watch those bugs tagged moreinfo and make sure that those bugs get their info, so the packages get ready to get removed - or the bug closed.

Everyone is welcome to edit ftp.debian.org bugs, as long as those edits make sense.
