I tagged one of my own works with second_life just now, and did a search to see what else was using the tag. To my surprise, there was a lot of traditional art using the tag.
I can see the tag is marked as a 'copyright' so it's clear that the curators here know it's meant to represent the online platform Second Life.
Therefore, I wanted to ask if it's okay to remove the tag from art which has clearly been drawn and not rendered from the game? I assume people have simply misunderstood its purpose, but I don't have as much tag experience as you guys. On the bright side, there only appears to be two pages' worth of submissions using it, so it would be easy to judge and fix the majority of them with just a glance.
