Neutral
I think Shank and Gunner summarise my position on this actually, and they've made some decent points in my opinion.
Just a couple of things I saw others mention which I thought would be worth touching-base on:
If you click 'Disconnect' then you disconnect immediately. But if you were to just unplug your PC, your player and entities hang-around for a few mins from my experiences.
I would argue that LTAP (Leaving to avoid punishment) doesn't apply in this scenario. It's certainly FailRP without a doubt, but the FailRP was leaving in-itself. You would have to rejoin, be brought to a sit, then leave a second time knowing that you'd been reported, for it to be LTAP in my eyes.
Even No Intent to Roleplay (NITRP) isn't a good fit for this given that it's for when multiple different rules are broken, as opposed to one just one instance - you could otherwise argue breaking the vast majority of single rules is NITRP, so it's best to keep it separate
I think there's a couple of options that would work best:
Make a new rule specifically for 'Intentionally disconnecting during an RP scenario' which would also apply to mugs, being arrested, and a whole host of other things too. I'd add that this should not be overly harsh (must be proportional) and should not be up to staff discretion, as over time ban lengths exponentially increase when left unchecked (I think the average first-time racism ban is now like 5 consecutive life sentences when it actually started at a discretionary 2 week ban with typically a verbal warning first). Perhaps a system of incremental increases, by number the of previous bans, as a better solution?
Shank's idea of delaying the de-spawn of entities for 5-10 mins after you disconnect would be a good solution, by eliminating the root-issue without the need for another rule and associated moderation
