EDIT: Discussion is moved to meta.SO: Policy of questions which are wrong/have erroneous assumptions
I could not find any discussion of this issue so here it is.
I have been involved in helping a user with the externalization feature of tikz
. The user first thought that the problem had to do with a loaded library from tikz
. See: https://tex.stackexchange.com/q/40511/7049.
But in fact the question is wrong in context.
I pointed this out to him, and he correctly posted a new question (although he could have edited the present question, but nevermind that). The question now resides: References in externalized pgfplots. Good!
The moderators have closed the question as too localized. However what is the policy on questions that are actually wrong in the leading thoughts on error? Are they simply closed or should they be removed as they provide wrong information to new users?
I am in favour of totally removing the question as not to show up when other people search StackOverflow on these terms. But would love to hear other opinions!
