This looks hard to prove.

On the other hand, everyone can check that you confessed to ban evasion on your site http://www.actubitcoin.fr/les-membres-de-bitcointalk-veulent-virer-davout-david-francois-bitcoin/ - everyone can also check that your website, supposedly dedicated to "bitcoin news", mostly contains libel, harassment or disclosure of private communications specifically targeted against Bitcoin Central and their employees, then draw their own conclusions.

IMHO, you should also consider yourself lucky if they don't press charges.
