1. block the "host" acc and enable IP autoblock

2. block the suspected sockpuppet and also enable IP autoblock

3. check the list of all blocks. if there were two autoblock entries recently, that means they're not sockpuppets. if there was only one, they're sockpuppets.

sorry if you already knew this
