Joined in September 2017, was mostly active in the Maps and Graphics Forum.
Only lasted for a little over two months. Jack was focused almost solely on self-presentation and showing off, to the point that he made two almost identical threads in quick succession, wanting others to provide content for “his threads”, and form some sort of parallel community in his threads. (Bizarre, to say the least.) He also started attracting the ire of mods for repeatedly spamming the map threads with images, often unrelated to their subject matter, and for other low-effort posting. He showed a genuine unwillingness to comprehened what he's doing wrong and acted dismissive towards others when told politely to clean up his act.
