Special amnesty 2014
Dear users,

Site and hardware updates create a great moment to do a more in-depth site cleanup. Hence we are will purge all disabled accounts from the database, kinda 'starting afresh'. If any of your friends have been disabled and would want their account back this would be a good moment to recover it. This special amnesty 2014 will run until the end of February.

See this forum thread for details and a public text to copy.
