The admin and mod team had a very detailed discussion about this whole thing back in May and June when this all kicked off. We discussed various options, which we let everyone know about and we were very proactive into looking at how to implement the various options.
We tried to implement making tags public, but the issue with this was that it opened a whole new can of worms because it made all historical tags public, and there was at least one issue where an off-colour tag had been left in a joking manner that could have been construed as something else. There are potentially more there, and I think it would be a huge job to go through them all. I don't think it's fair really to turn them on for historical tags, we do not want to turn this into some sort of historical tag hunt.
We looked at making the tags known only to the admin and mod team, and if someone has an issue with a particular tag, then they would notify us, and we would deal with accordingly. We discussed how we would do this.
We then got a White Lives Matter tag, which ended up being deleted before we had the chance to do anything about it. At that point we had reached our limit and we decided that the best thing to do was to switch off the tags at that point. Which we did.
The time out was just as much for the mod and admin team as for the whole forum, it was just not a good time and lots of people were getting upset both on the mod team and off it.
That's about how things lie at the moment.
