Thanks.
1) In the Comment Blacklist section of WP I added part of the spammers who is address. Will this step block this person from spamming me? https://whois.arin.net/rest/ip/
2) In the section on combatting spam I found this but I can’t find the following line of code anywhere.
<p>
<input name="submit" type="submit" tabindex="5" value="<?php _e("Say it!"); ?>" />
</p>
Inform Users When Comments are Moderated
When people submit comments, they expect them to appear on your blog immediately. Implementing comment moderation and not telling people will almost certainly result in some people repeatedly submitting the same comment as they think it has disappeared. To prevent this from happening, and to avoid disgruntled and confused readers, inform people that their comment is under review by doing the following:
If you use popup comments, edit comments-popup.php and if you do not, edit comments.php.
Look for the following code:
<p>
<input name="submit" type="submit" tabindex="5" value="<?php _e("Say it!"); ?>" />
</p>
Change that to the following, adding your own customization:
<p>
<blockquote>
Comment moderation is in use. Please do not submit your comment twice -- it will appear shortly.
</blockquote>
<input name="submit" type="submit" tabindex="5" value="<?php _e("Say it!"); ?>" />
</p>
