To be clear, this should already be the case thanks to the policy update a few months ago, but AFAIK there was no notice to existing users unless you were logged in at the time or dropped by the forum, so I still have to remind the occasional player from time to time.
As for the wider issue, there’s a (sort of, actually not) simple solution: turn top-level areas into realms* linked by fast transit (or alt. profiles per realm?), ideally retaining the top-level realm activity list, restricting Awake to the current realm (unless switching to ‘global’?).
That way, if you don’t go to Lamplight, you don’t get squicked by the cubs there; don’t go to Umber, don’t get spooked by gangsters; don’t go to Ravenholm, don’t see icky zombies; etc. (Also, the list is more manageable and you don’t walk about wondering why you can’t find X.)
It could be enough for some just to area-filter Awake, albeit this would result in less isolation of ‘extreme’ content to standalone data stores/domains.
Even easier should be ‘tag blocking’, as it can already be done for Awake with the filter system - but I doubt people want !ageplay there all the time to remind them, hence the need for a separate list that could come with helpful suggestions to add.
I recommend this be done ASAP, as it may solve or ameliorate the issues some seem to face, while not putting any onus on other players who happen to be using the same service for their own enjoyment, and who aren’t to blame for others’ reaction to their very existence.
(*The linked post expresses a desire not to split Wolfery’s community, and this could be a way to do realms while still making it feasible to ‘sell’ the idea to furry members, e.g. those seeking to create an [official?] implementation of Chakona Space or Hayven Celestia.)
