Add Origin via IP address Tracking
Comment section on YAHOO has been overwhelmed for some time by trolls, bots, & bad actors. I am NOT suggest you moderate or censor your platform more. However, you COULD let your users make intelligent assessments regarding what they are seeing.
A simple addendum to users' icon or name - flagging country of origin and/or VPN usage by tracking IP addresses.This would be a quick and relatively easy 'fix'.
Per the TOS everyone accepts without reading, YAHOO does collect and track IP addresses. You just need to make it transparent to the users.

I support this idea. Or, just disable comments entirely.
