omg the thought of this is terrifying!!!! And I really agree with @BlackRose108 They need to make it harder to delete your series.
I'm going to email them and bring this to their attention, anyone else who agrees should email them too because if enough people complain they may change it.
I'm going to ask that they do 2 things to make deleting a series harder
1)move the button so it's not next to all the important buttons like edit, or even the scroll up and down side arrow thing on my desktop)
2) they should require human authentication (Ask me for my login and password for example) before I can confirm.
Imagine leaving your account open and an angry sibling just decides to delete it- oh the horror.
I think it'd also be great if they made it more annoyingly alarming (Bright Red/ Yellow type of popup that is like WAIT ARE YOU SURE YOU WANT TO DELETE EVERYTHING?) Like don't make it look like all the other stuff.
