I'm no admin/moderator, so I'm not sure whether discussing the rules is technically against the rules...However, note that nothing I say is set in stone - I'm just another player like you.This isn’t the place to get info on the writer rules? If players are going to get banned for things shouldn’t the rules be in writing? I’ve yet to see anything about “botting” “afk”
As such, I would hazard a guess that simply being AFK is not a problem. That, however, is what the automatic player timeout is for - if you don't do anything for 5 minutes, you will be disconnected. If you work out a way to get around that, whether it is via external software or tapping occasionally every few minutes while not paying attention, then it gets a bit hazier and harder for VR to tell the difference.
You seem to be right though, I scanned through the Terms as well as several of the other rules, and didn't explicitly see anything related to not allowing the use of automated software to play the game (though I don't speak Lawyerese, so it's possible I simply missed it). It is against the rules however, but the rules should be updated where they are viewed publicly.
On a somewhat unrelated note, after digging through the forum rules, the mods/admins are really going easy on a lot of forum users lol.
