does anyone know how to fix this?
Was there any progress mage on this issue?
I missed this ... Damn ;(
A user submitted image gallery where you can comment and rate pictures. <sigh> hopefully someday.
NodeBB core doesn't have anything to prevent this. But plugins can be made to prevent multiple accounts from the same IP etc although it can be easily by passed.
@jiangcaiyang you can use these hooks for plugin activation, deactivation and uninstall
