Thank you very much for your kind offer!
I deleted the 60k spam entries by myself. I’m glad that it didn’t take more than half an hour. Most of the entries had the same fake email adress, so I could delete many entries together.
After half of the delete work (30k entries left) I checked whether the entries section in the WP backend was back. It wasn’t. But at the end, when I was done, it reappeared – great.
I hope that with the mathematic anti-spam measure and the anti spam plugin webvitaly suggested I won’t encounter any more spam in the future.

Thanks everybody. I’ll give Anti-spam plugin a try in the future.
Do you have any suggestions why the Entries moderation section in the WP backend is empty?
PS @ DanielSchurter: There’s also nothing listed under “Spam”.

Thanks a lot!
I looked for that thing in the functions.php of the Pinboard theme. But there was quite a lot of code that has obviously to do with it. Could you push me to the right thing to change? Unfortunately I’m a total PHP noob.

if ( ! function_exists( 'pinboard_post_image' ) ) :
/**
 * Show the last image attached to the current post
 *
 * Used in image post formats
 * Images attached to image posts should not appear in the post's content
 * to avoid duplicate display of the same content
 *
 * @uses get_posts() To retrieve attached image
 *
 * @since Pinboard 1.0
 */
function pinboard_post_image() {
	if( has_post_thumbnail() ) : ?>
		<figure>
			<a href="<?php $image = wp_get_attachment_image_src( get_post_thumbnail_id(), 'full' ); echo $image[0] ?>" title="<?php the_title_attribute(); ?>" class="colorbox" rel="attachment">
				<?php the_post_thumbnail( ( pinboard_is_teaser() ? 'teaser-thumb' : 'image-thumb' ) ); ?>
			</a>
		</figure>
	<?php else :
		// Retrieve the last image attached to the post
		$args = array(
			'numberposts' => 1,
			'post_type' => 'attachment',
			'post_mime_type' => 'image',
			'post_parent' => get_the_ID()
		);
		$attachments = get_posts( $args );
		if( count( $attachments ) ) {
			$attachment = $attachments[0];
			if( isset( $attachment ) && ! post_password_required() ) :
				$image = wp_get_attachment_image_src( $attachment->ID, 'full' ); ?>
				<figure>
					<a href="<?php echo $image[0]; ?>" title="<?php the_title_attribute(); ?>" class="colorbox"  rel="attachment">
						<?php echo wp_get_attachment_image( $attachment->ID, 'image-thumb' ); ?>
					</a>
				</figure>
			<?php endif;
		} elseif( false !== pinboard_get_first_image() ) {
			if( ! post_password_required() ) :
				$image = pinboard_get_first_image();
				if( false === $image[1] )
					$image[1] = 695;
				if( false === $image[2] )
					$image[2] = 430;
				$attachment = get_post( get_the_ID() ); ?>
				<figure>
					<a href="<?php echo $image[0]; ?>" title="<?php the_title_attribute(); ?>" class="colorbox"  rel="attachment">
						<img src="<?php echo $image[0]; ?>" alt="<?php the_title_attribute(); ?>" width="<?php echo $image[1]; ?>" height="<?php echo $image[2]; ?>" />
					</a>
				</figure>
			<?php endif;
		} else {
			the_content();
		}
	endif;
}
endif;

Do you mean this? It comes directly before the code quoted in the opening post.
<?php $args = array( 'posts_per_page' => get_option( 'posts_per_page' ), 'paged' => max( 1, get_query_var( 'paged' ) ) ); ?>

No, I haven’t read “a page of posts”. Unfortunately I don’t understand PHP the least, so every code that is different from what I see is immediately confusing for me.
