I'm not sure if there're more. Take a look at the threads, especially the second one.
(2) A thread was posted asking if this was ethical

Going to his flickr gallery, you would see more photos plagiarised. Note that copyrights on these photos were removed. Some photos belong to Clubsnap members, others belong to Airliner.net.
(3) On 21 Mar, at least one attempt was made to PM him (read somewhere in the middle of the third link). He replies and maintains that the photos are his. His last logon was yesterday just after 1700 hrs, so we know at least up till that point, he could still log on, reply his PMs and had the opportunity to send an apology. None was given.
(4) Late afternoon 21 Mar, he apparently deletes his flickr account. All pictures disappear.
He remains quiet in Clubsnap but remains active in the Hardwarezone forums, offering opinions and advice. Members start getting worked up due to what they see as an attempt to pretend that nothing has happened.
(5) Evening of 21 Mar. Attempts were made to contact Timber Wolf who is known to know the guy. Timber Wolf talks to the guy. So now the guy knows he has been traced. The guy claims it is a misunderstanding and Timber Wolf posts in Clubsnap as such. Members direct Timber Wolf to previous posts and pointed out that it cannot be a simple misunderstanding. Timber Wolf talks to the guy again who says he will offer a public apology.
(6) Public apology is given. Public apology however continues to maintain that there was never an intention to pass off photos as his own. CS members refer again to
http://forums.clubsnap.org/showthread.php?t=172435 as well as the removal of copyrights in the A.Net photos where there is a clear intention to deceive.
