Even if he did "steal" the egg, doesn't give you the right to kick him from a game. You should have played it out then requested a ban for him (if this is even a bannable offense). You took your admin powers and used it in game. I believe this is admin abuse. Nowhere on the I.D Rules does it say it's an offense to do what Zaq did.
[spoiler=]Island Defense Rules
Reasons to temporarily ban or kick a player:
If player is not punished in-game, then we can enforce a time ban.
AFK builder/titan that ruins the game.
Placing your main builder in a place that is not nukable by titan.
Loud stacking (worker stacking with the loud error sounds) or worker stacking in an unnukable spot in a base.
Intentional stalling a losing game as titan and wasting everyone's time for more than 5 mins. The titan can be kicked if he does not kill a builder in 20 minutes time, and if 50% of the builders alive agree to having the titan kicked.
[Reveal] Spoiler:
Intentional feeding without 60% of the other players' consensus (applies to titan intentionally feeding builders gold).
Refusing to leave base after being asked by owner.
Item stealing.
[Reveal] Spoiler:
Intentional abusing of pause/resumes and/or save game.
Intentional suiciding that negatively affects the game (unless to deny feed or the game is blatantly over and no builders want to take over titan).
Intentional blocking that negatively affects player(s) game experience.
Any form of glitch abuse that negatively affects the game.
Team killing (denying feed acceptable).
Leaver titan in the first 10 minutes of game (time must be noted from when titan spawns (GP timer starts)).
[Reveal] Spoiler:
Player enables game modes -ar; -rd; -br; -gc; froff; -exp/dxp without 60% of the other players' consensus
Multi-boxing
Use of Macros that significantly alters the game-play of the player.
Stackable time bans for repeat offenses of any of the above.
Refer to [General rules] for more information on bans and kicks.
Note: Item jumping, titan mass-jumping and wall walking are not punishable by ban.
Miscellaneous Rules:
Titan may leave the game under the condition that 3 or more builders have left the game or became observers as a builder in the first 10 minutes. He can also leave early if there is no basers left (Builders that have already died to the titan are not counted).
Gathering consensus in the lobby chat is not recorded, so it is still bannable if you do not have proof of lobby chat, unless an ID staff member confirms that 60% consensus was gathered via the lobby chat.
If a player pings a seed and/or a base it does NOT mean they have the rights to that seed and/or base. The first unit that has the ability to build (includes any builder/summoner, excludes nature's workers) to the seed and/or base has the rights to it. Tk'ing will result in a time ban.[/spoiler]
