I have an issue that is occurring on one of my sites that I have no idea as to why it is occurring and it is kind of freaking me out.
Recently, I put out a promotion for one of my sites, and I noticed that after I did that, one of the visitors apparently looked over my site and then proceeded to visit just the home page every few hours.
I did a blacklist check on the ip and found that it did appear on several of the blacklist sites so I went ahead and blocked it. That stopped the problem from that ip.
But, the next day, I noticed that someone visited from another ip within the same city without a referring link and started visiting just the home page every few hours. I checked that ip, found that it too appeared on some blacklists and proceeded to block that as well.
I have been repeating this exercise every day for the past few weeks, and every time I block an ip, a new instance occurs of someone just visiting the home page every few hours. Some of the ip's appear on blacklists, some do not. But if I do nothing, it just fills up my visitor registry with these bounces.
Can anyone explain to me what could be happening here? What benefit would anyone get from just visiting my home page and leaving other than helping to raise my bounce rate?
Could this be a setup for a more malicious attack? What can I do about this?
Thanks to all who can help.
