I, which afaik, im the OP, are not demanding server admins (or bans).
Your three server admins on your unofficial server would probably have closed their server, if they had to take care of all the bugs and mechanics FunCom fixed since release, because they would have been non stop taking care of stuff. How do I know?
Played more than 100h across a couple unofficials (arkuna matata, resurgentes, go check in battlemetrics if you need xD), since release, where there was no purge, no decay mechanic, no no build areas on camp thralls, killable thralls on pve, etc. Admins were going mad trying to solve all those issues. FunCom made fixes, and admins now only have to concern about a much smaller amount of cases. Which as you said, 3 admins still struggle to take care of an unofficial server, AFTER half a dozen fixes that took care of griefing methods.
I stated in my OP "Hey, I have no problem, I can survive to that! " so its not a bigger problem for you than me. Killable thralls on PvE were probably a bigger problem for others than for me (ala they suffered it more and felt even worse) but it was me (mostly, not wanna take credit about such a pointless “achievement”, but its the truth) that acurrately reported it here, on twitter, and we got it fixed.
Also, reviews for survivals without officials would have been much more positive, I agree. While much much less popular, due to the lack of them.
