Obviously, they decided that my site was no longer acceptable and they set up specific rules so that tumbex users no longer have access to the contents of tumblr.
It is therefore with great sadness that I announce that you are living the last moments of tumbex, it was a great adventure, and a big thank you to all those who have followed me during all this time! We take no responsibility for the content on any website which we link to, please use your own discretion while surfing the links.
