I discovered today by coincidence that my site had been hacked. Someone put in code to place a bunch of invisible links in my footer file. I have fixed the problem but its very frustrating to see something like that on one of my sites. It also explains the fact that this site has been penalized by Google and given a PR of 0 (which I noticed on Friday).
I wanted to apologize to my readers, especially if any of you have noticed this. This type of malicious behavior is very frustrating and so pointless since it probably didn’t drive any traffic to whoever was doing this.
