::1. Change your signature.  You were given plenty of notice and you still haven't. 
 ::2. You do not set the terms for blocks, and saying someone will be blocked for 3 months or 3 years shows an amazing lack of clue.  That isn't the reason you were blocked, but it is inappropriate and I support both the block and the modification to your editnotice. 
 ::3. To say "No one has vandalize my page" and attribute it to that notice is silly and again shows a lack of clue.  You might as well say "I stuck a banana in my ear to keep the sun from exploding, and so far it works!".    -   -  - @ - Join WER
