Charming Etiquette (from other camps)

[Taiku]

I was at the goblin camp in HHK, I had Osargen charmed (and had him charmed for about 5 hours before this) while grouping, a druid came up and said "oh... you have osargen..." "rip wanted to camp for xp :/ guess im screwed" And then proceeded to /tell me "with you cahrming you are claiming 2 camps which is illegal, in the discord getting all this info, please drop osargen". Followed by a bit of bickering in /ooc, I didn't respond to any of it (but my group sure did). My group mates assured me that I was fine to keep him.

They ended up logging out before anything came of their claims of "reported you for scumbaggery", I thought it was quite rude to demand me to drop my pet!

There is no loot off this mob aside from the mage weapons we had given him, and he backstabs so he's superior to other mobs in the zone for charm dps.

Was I wrong for not dropping the pet so this druid could camp him? I want to get a clear understanding of how this works to avoid future conflicts as I am new to enchanter, thanks!
