Shadow's Corner refers to his enlisting bh's to his way of thinking and that if your bh does not agree with it his bh and all those who agree with him to not allow your bh to hold even one P . My bh took one and we were told to move so we go to move the next morning and every single P on the server was taken .
Don't know which BH is yours, but if you're afer a single Presidio, that can be defended if everyone participates. Simply put all the BH def there (where else to use def anyway?) and, even if it falls, it'll be waaay more expensive for the people attacking you.
Alternatively, you can talk to the big players and ask If they'd be ok with you taking some specific Presidio. A bit of diplomacy can get you a long way.
Of course, if you want to go big, then your BH is likely in for a fight, but that's not really surprising, is it?
SYC will leave the game and take money with them if this is the way of the game plarium can gfts.
While I don't like it if some players bully others, what exactly do you expect Plarium to do here? It's not cheating or anything like that. Someone is legitimately stronger than you and acting on it. I gave you some suggestions how to deal with it, but if you expect Plarium's intervention... what exactly do you think that they should do?
