Comment (by wildintellect):

 I managed to dump what I think is the last months worth of user
 registrations, with creation times. IP is not a stored attribute from what
 I can see. There does seem to be a spike the last few days, and I can
 easily make a list of the accounts (though no way to tell which are spam
 accounts). See attached plot of the trend over time (will share R code
 later if people want it).

 {{{
 ldapsearch -H ldaps://ldap.osgeo.org/ -b dc=osgeo,dc=org -x
 "(&(createTimestamp>=20160401100000Z))" + > osgeoldapsince040116.ldif
 }}}
