Answer 1

You're not implementing the method signature when extending BaseBlockService.

use Sonata\BlockBundle\Block\BlockContextInterface;

public function execute(BlockContextInterface $blockContext, Response $response = null)
{    
    return $this->renderResponse('InstitutoStoricoNewsletterBundle:Block:block_my_newsletter.html.twig', array(
        'block'     => $blockContext->getBlock(),
        'settings'  => $blockContext->getSettings()
    ), $response);
}
