I'm a woman of colour and I blog about racial justice and feminism. I noticed that my blog was being linked to a racist/white supremacist site through the "possibly related posts" links, because it all seems to operate on keywords. Minutes after noticing that, I got a troll commenting at my site. I'm really wary about this because earlier this month another woman of colour blog was attacked by white supremacists. I blacklisted the IP address of the troll and disabled the Possibly Related Posts feature, but it doesn't deal with my concern about how prone to abuse this feature is. Especially by sites with extreme right-wing content, or which target social justice movements, since sites like that would naturally use similar terms to those in social justice blogs and they've attacked bloggers in the past.
What, if anything, is WP doing to deal with the high potential for abuse that this feature brings?
