hackers on forum

[Local Chap]

And a curious thing too on the "threads in forum" page of the Forum Readme sub-Forum (and now I see the same thing on other sub-forums, eg TAC HQ).

Many of the threads are started by Geoff Winnington-Ball, some have replies, some do not. Where Geoff has made the latest reply, his User ID is shown as "Winninion-Ball", while there is also the occasional one by "Geoff Winnington-Ball". I thought this might have either been a new account created by some other person, or the hackers had got in and changed his account out of disrespect.

Why is it so?
