Until yesterday i had a good traffic and 59 domains pointing to my website. This morning at 4h00, webmaster tools updated the number of inbound link to 69. At the very same moment, my traffic almost entirely dropped to zero. I checked the 10 new domains and they are ok. 50% of them come from blogspot and wordpress. They are not banned by google. I have the feeling there is like a penalty. It is strange because 10 domains is only 15% of 59. Did this happen to anyone here?
