You really think they are going to put effort adding all of your sites? They can't even determine which ones they are.
I already got the answer it was someone with access The question now is..... if one site goes Black Hat by buying links... can the other 10 White Hat get in trouble
Never heard of this happening to anyone either could it be something to do with your google analytic's account being combined to webmaster tools and in some way they've been exported into tools? do you even have these accounts combined? wow you got 'googlefied'....lol.. ROOFIS
Buying links is really more grey hat than black hat. Black hat is much, much more sinister. Things like bounce attacks, automated web scraping, and lots of other evil things.
Oh and to answer your question, buying links will not get your other sites in trouble (unless they are really bad links, like link farms, porn sites, etc). Google is pretty hypocritical on how it handles paid links.
google is wast and google is more powerfull then us and google makes everything fare and if one domain is black hat then the rest too get black hat
You are right, google employees have hacked into your computer, and are using your own web cam to monitor your activities. They plan to steal your 10 websites and sell them for $100.00 each, and then.... They will take over the world.
Google webm tools doesnt automatically add sites to its account based on ip unless you or someone else added and verified those individually.
