cotp on "[Plugin: Wordfence Security] Reporting IP of spammers ?"

Thanks Mark for your answer,

Where in the plugin do I activate the Wordfence Security Network ? Is it in the Options page ?

Is it also possible to export the list of bad IP and block several IP at the same time ? I mean to share the bad IPs I have blocked between my sites ?

Thanks

Cotp
PS: By the way just for curiosity how do you filter ? Is it by the number of connections attempt ?
