There are plenty of game moderators on at all times of the day. You can use /staff to message them if a situation ever occurs. In the case of making it so room hosts is unkickable wouldn't make sense as there is always two sides of a story. Yes it's shitty that you have to go through this but rather than creating a feature like this which I think has more negatives than positives, record and post on forums(that is if you aren't able to get in contact with a staff ingame).
