removal of a science refdesk query hi ten i just spent about an hour composing a detailed reply to a seemingly unexceptionable science refdesk query about frogs and toads which had already had one routine but brief answer from regular contributor kainaw only to find that when i save paged the whole question disappeared as far as i can tell from history which i'm not very conversant with so forgive me if i'm mistaken you were 'reverting a banned user ' i'm sure you had a good reason for the action but for my own curiosity was the banned user the op can you link me to the reason for the ban what tipped you off given the innocuousness of the query and is there a handy list of banned users i should check before answering apparently innocent queries to avoid future wastes of time
