Alright, so I've been getting kicked a lot earlier, so I ran some tests, if you can call it that. What I found is that, for me, killing the NGS process actually causes my kicks. Or at least, some of the kicks. Prior to the test, I first removed all the mods, (unless something was leftover that I didn't catch), but Abyss was definitely gone.
Then I started a client, didn't kill NGS.
Then I added in Poison Pack while first client was open, and opened a second client with the added Multiclient
Then opened a few more clients, logged into a bunch of accounts to pass the time, didn't get kicked from either clients for about 25 minutes or so.
Then I killed NGS and shortly (a few minutes?) after both clients were terminated.
Not sure if killing NGS triggers the termination for sure, but it does seem to do something.
Hope someone can make something out of these results.
