I noticed something about this user, almost all questions they ask are answered for them in comments or by other users and they take this information and create there own answers with it and accept it, just look at there question history.
Here is an example,To sync notes of S Memo to Ubuntu? , a question that was answered, not accepted and then the user put the information from the answer, in to another answer, made it a wiki, then accepted it.
I don't know why they are doing this but something seems very wrong here, is it just me or is this very strange behavior?
I think a mod should take a look at this, while self answers are encouraged, it should not be at the expense of other users contributions.
