xD Wow, all of these stories are amusing to read. I almost feel sorry for the powerplayers.
Welp, to add my own story into the mix...
When I first started out in FH, I made a pack. It wasn't much of the strict, literate packs you may normally see in FP, it was just a fun place to chill, chat, and rp if ya felt bored. It became rather successful. I remember maybe three, four weeks after the group was made, I was roleplaying and chatting with some friends under a tree which we called the pack's home. All of a sudden, another pack comes up to us. The leader, a beta I believe, and maybe four or five other members were with them. All of the sudden, then leader starts rping with us, without asking for permission, saying stuff like "You are in the (insert name of pack hither)'s territory."
Take notice that we did not see this pack around the area before, nor did they come back after this incident. The posts were like normal roleplaying posts however.
Ex: The brute walked up to the splayed out leader of the rival pack, his teeth bared into a snarl. "You must get out of our territory, or else."
It was clear that this leader was territory claiming, but through roleplay I guess they thought it wasn't official territory claiming.
I didn't mind having the pack roleplay near us, which I told the leader several times OOC, but they continued posting rping posts. In the end, I went along with it.
I started rping with em, saying stuff like...
Ex: The grey pelted leader shifted his weight, and looked to the other canine. "Well, I didn't see any markings" he laughed.
Sort of stuff like that.
While between posts, I was still trying to talk to the leader and members OOC about territory claiming and how it was perfectly fine if they wanted to rp near our pack, but in the end, the leader attacked my character IC, and then the other members started attacking my members, who were just silent, watching the scene play out. They started "killing" our characters no matter what we said, even when we stopped "playing along" with their rp and fell silent. Eventually, we just blocked them all and continued with what we were doing xD
