Well if you want the book, you need to give your game data id and passwords. (Maybe even emails. Im not sure abt this one). It can be counted as force? Ofcourse!, especially because only around 3 guild or less from there "get turns" to kill the raid bosses. But if you dont want the book, then its all good. So maybe we can say it is an abuse of circumstances.

That's insane. I can't let some turd run over me in a video game. That's why when I do play or be active, I keep my guild invitation off. I'm not letting some clown think they could force me to do whatever. A lot of WS players need to break the bs cycle. 

It happens, and well known in EU-Emerald apparently. I'm sad for my friends there!

Wtf. 

I understand your concern, but i think its way more balanced if it was changed like how Ogull suggested. Like nowadays in US server people will pm other guild to ask "Why did you steal raid boss?" As if its theirs. And even worse in EU. People need to give their id and password to their guild leader if they won the bid of sea books, so that they can banned that char if somehow he moved to other guild or sold it.
