dis.tinychan.net is dead because it was a victim of its own success. It was so popular that it attracted too many trolls, spammers, bots and hackers who flooded the site with garbage posts and malicious attacks. The site's admin tried to keep up with the chaos, but eventually gave up and abandoned the site. The remaining users soon lost interest and moved on to other sites. Now dis.tinychan.net is a ghost town, haunted by the memories of its former glory.
