You have, according to real proof:
1. Made multiple accounts on flickr to harass Wanderer.
2. Made multiple accounts on Reddit to harass Wanderer.
3. Have more than one account on DA, probably to harass Wanderer and other artists.
4. Have multiple accounts on Twitter, according to records.
5. Found multiple accounts of yours on FB.
6. Have repeatedly gone around blocks and bans, using different methods, including making new accounts and logging out (according to you) to avoid a block.
It really isn't hard to believe that you would have more than one Tumblr account.
