I checked my logs (for a different reason and found this... never install into the default directory and ALWAYS change your xmlsrv and xmlrpc to something non-standard... then update the config file ;). That is how so far I have come to be not spammed... and no pingbacks :) I have been very lucky to not be harassed by bots.
