Yes.
You work with them, you give them other options, you may even consider negotiating with them as an act of desperation if you're operating from a weak position, but eventually as a leader, you need to pull the trigger, boot them from the tribe, mark them for immediate elimination, and kill them and take their stuff. Maybe not necessarily in that order, mind.
If you do nothing constructive, take resources from members who would otherwise better utilize them, *and* simply sit under our umbrella for protection, you're of no use and will be eliminated as soon as is feasible.
I'm sometimes considered a carebear/TribalHugs player and even I set those guidelines.
Playing devil's advocate Hopeless.
I've had to order people to be eaten, mostly inactive, but there have been actives that have been ordered to be forcibly removed from the tribe by way of the rim. For various reasons and not always for the best of reasons (best reason to in-tribe noble a player = spy, those have been the most fun and usually entrusted to the most loyal player who is the closest, bad reasons? Anything from the barons deciding that person wasn't being active enough to sniping incidents where the sniper didn't back down or someone trash talking the tribe and getting members riled).
I'm a bit more ruthless with inactive players and those who never or rarely participate in ops but have the ability. Players who are account sat by another tribe without permission from the duke(s) are immediately kicked, given 1 day to explain themselves then put on the noble list. If they're not back in that one day, oh well. That was something myself and the 3 main barons decided. Banned players had another rule. I'm not going to explain what we did with those who refused to be in any op (in-tribe or out). A couple of people might come up and say they knew cuz they were barons at the end... but by then, things had already started to get fuzzy and the rules weren't always adhered to.
When 1/3 the tribe goes inactive at once, it does present a lot of problems for leaders. Especially when some of those were being counted on for ops and had just been active the week before or 2 days before but upped and disappeared. Sat accounts when both the sitter and sittee were to be counted upon for an op presents yet another problem. But when a player deliberately attacks 2-5 days AHEAD of time on a major op, whose fault is that? Seriously now. You tell the player "in your time zone, we need you to attack at 9pm from your villages in the 470-495|320-360 ranges" and they attack 5 days early? This after you've used server time the LAST time and they confused it completely. "We want the attacks to LAND at xx:xx server time on xxx|xxx xxx|xxx and xxx|xxx villages; please use one of the tools given or your map if using premium to determine how early to send" Only just so much you can do when that person had been a regional commander who had planned attacks and later a baron. But still attacks 2 days early on one op, almost 5 days early on the next one given to him. I don't know about JP's attack plan, this one was one I knew of from awhile ago vs UNIRO then TSC.
So the above question Hopeless really was playing devil's advocate. Some things the leadership can do to help remove inactives, some to motivate, others to remove completely, but if a player has RL or boredom happen upon them without any warning to the leadership, it is difficult to move.
It's also up to the players...... if they don't want to play under someone, leave/change tribes/shout it out/say something. Personality conflicts can be worked on - others might be directed to deal with those players instead (barons or another duke).. lots of ways to resolve conflicts, but when players deliberately do something to upset the tribe (yes, i'm in for that op - and then don't show up until 2-3 days after the op goes off or attacking early) then it's not on leadership for those. When that happens a lot within 2-3 ops, it's a major problem and how do you cut 1/3 of the tribe (or more) without causing chaos/anarchy?
Members should be looking to the leaders for guidance. Really, leadership has enough to do without timing your attacks to the second. And then to find out you didn't help your tribe? But still blame leadership? Oh wow, love it! Don't take responsibility for what you do with your account and you saying "yes, I will be in that op" - there's enough responsibility to dump on the leaders and everyone else wants to blame them because you felt like going out that night (last minute) to ..... roll someone's yard or something else equally pointless and criminally destructive. Blame that on your tribe leaders too. It's their fault you were so bored with the game that you had to find something in real life to destroy. Nice. (yes, one member was arrested one night for egging and rolling someone's yard - did some other major vandalism as well - enough for a felony charge - and yes, he was supposed to be in an op that night but had just disappeared - couple days later went yellow and he got assigned out not long after that) - must have been the leader's fault.
