Recruitment centers are all bad. They're just a way for clans to demonstrate activity without risking being beat. They include swords as defense weapons and are all derived from that of VAK's.
tbh I just go to every recruitment center I see to see what kind of design they have. I have found 3 used by major groups that have been copies of my design.
I generally visit most forts/bases I see. I can't imagine that those groups who used copied versions of your work got very far--so I don't think it's much of a worry.
