We have been discussing purging unused user accounts on the OpenOffice.org Wiki.

I can run the removeUnusedAccounts.php maintenanace script, and it will happily remove all unused accounts (that have zero edits)... the patch suggested on the Discussion page for http://www.mediawiki.org/wiki/Manual:RemoveUnusedAccounts.php allows me to set the age of unused accounts.

Is there any guideline that people use for how old an unused account should be before it is removed? Is it 10 days, 180 days, 365 days?

Does anyone change the query so that the script checks for unused account that has not been logged into in X number of days? Is this possible?

The concern I am hearing from the OOo Community is that we may purge accounts of Wiki users who have created an account, but not yet decided to make an edit. I'm wondering how other Wiki admins manage this...
