Let me start out by letting everyone now that I'm a former Nuke user. It's a great program, however if one doesn't have the time to sit and "guard" it, bad things can happen. I cut the cord on my site after it was hammered 200 times by numerous porn sites within 48 hours. All the known tricks didn't help.... >:-/
Part of the problem is a group of hackers from Brazil & Russia take great pride in doing Google searches and hacking peoples sites. While usually they do not do much damage other than taking liberty of adding themselves to the "God" user list and leaving messages such as "I got your password" with some graffiti likes signature attached.
Since most do not want to pay the hefty $300.00 fee to remove the copyrights and links to Nuke in their meta tags, it was discovered that by scrambling the text, and including a image seems to have helped this "bot/hacker" problem.
Personally I don't like bots, but they are just an annoying part of the net that we all need to deal with. Are there ways to keep them from being less invasive? I don't care about hit numbers as they mean nothing to me. My site is nothing more than a way for friends and family to know what I've been up to if they shouldn't hear from me as much as they'd like.
And can the copyrights that is written into WordPress be altered? Either by scrambling/encrypting the code and or by adding a image? Images can be caught by spiders, but I can deal with that.
If I had my way, my site would be virtually invisible, however the only way for that to physically happen would be to only have a site in my mind, so I'm willing to compromise.
Thoughts on these issues would be greatly appreciated.
