If it breaks Fluther guidelines you can flag it, give your reason, and a moderator may remove it. If it doesn’t break Fluther guidelines it most likely will not be removed unless you can come up with a very good reason as to why it’s essential for it to be removed.
@downtide is right. You can certainly raise your concerns with @augustlan who may decide you have a valid reason for wanting something removed. There are no guarantees though.
Why would anyone refuse to remove an answer for a person? Why must it be a “good” reason? Isn’t the fact that I, for whatever reason, want MY answer removed sufficient? Would is accomplished by denying my request?
