Question:
My blog has been constantly comment-spammed, causing the database to overload.
Could these spammers be blocked out to remedy the problem?
Answer:
I advise you check your blog software. Most have add-in modules to better block spam and moderate comments.
If you have the IP address where the comments are coming from we can firewall out that IP. However this is rarely a good long term solution. Most comment spammers change IP’s frequently.
The best solution is to go to the homepage of your blog software and look for a comment spam blocker. You might also want to check the user support forums for you blog software to see what solutions others are using. Usually there is a quick add-on you can make that will block most automated comment spammers.
