If you see a considerable increase in the online traffic to your Internet site and if after you examine the visitor stats it turns out that it comes from areas around the world or from other servers, your website is probably being attacked by an automatic bot. These programs go through random websites aiming to log in to their administrator area by using a brute-force attack or to leave spam comments underneath any sort of article where this type of an option is available. Unfortunately, this is something quite popular lately, but if you know the IP addresses from which the attacks come, you may block them, so the bots will be unable to access your site in any way. Naturally, you may block IPs even if you allow only people from specific countries to access your website.
