Some community managers ponder deleting old, long inactive contributions, due to a lack of technical resources or a belief that those contributions somehow take away from what they are currently trying to accomplish.
This is something that smaller operations are more prone to do because they may be hitting the limits of their web hosting plan – the database is too big and it is hogging resources.
But, I believe that when you delete older contributions wholesale – not because they violated your guidelines or for a specific reason on an individual basis – you are damaging your community’s history and legacy. To remove them is to rob yourself and your members of the wonderful opportunity to look back and see where you came from. It is not unnatural for a long term member of a forum to look back at posts from years gone by and reminisce.
