I've had my two websites show up fine in google search for months, and then just in the last couple of days, they both no longer show when I search for my name. Completely ripped from google search. 

I haven't done anything other than add some similar content for my ABOUT sections for each site. One is my personal name as the URL and the other is my gallery page which is on a different URL. I would think that having some similar content on each of the websites I own would not be a problem, as this should be a common thing for people to do, right? Only a small portion is the same. Would google rip them both out because of this? Do I have to make sure my about pages are completely different in giving info about myself? That would be stupid, but I could do it. I have removed the content from one site already just to make sure.
Would someone be able to have my website removed from Google if they had some malicious intent on doing so? Could someone who sees me as competition showing up in the search do some trickery to get my websites banned?
Thanks for any suggestions you might have.
Also, I only have one link going from my personal page to the gallery URL, but no links going back to my personal URL.
Maybe google's systems freaked out over this?
