this is my experience, i bought so many pages with auto click (cuz i'm not accidentally left it out)
and until now my account still safe. but i always avoid FM and HP event (i won't show up in PVP event haha that's a high risk). and not to convert many books.
well, this BB start 23-27 and FM 22-25, so if you wanna buy the item, i recommend the well times is after FM event is over.
it's still have 2 days left for BB after FM.
