If you install Mail Filters how is the list integrity to be documented?

There is a serious concern that when individuals are 'filtered out of 
IETF lists' whether by official or unofficial means, that their voices 
are prevented from being included into the IETF standards process. Are 
there any thoughts on how filters in mailing lists should be documented?
