This isn't a troll post. In fact its all true, this is a well known phpbb error. I fail to see how this was insulting or antagonizing you. Infact the closest post to a derailer/troller post is Isachs initial reply, and even that's somewhat empty.Theres a bug in phpbb2 were if posts are marked as unread it goes to the first unread post since you logged in not the first unread post in the thread.
Hence why reading an unread post then going back to the thread after a new reply leads to the original unread post not the new one.
imo your just flamebaiting now, and your not doing it very well either...
