Hm... It's interesting to read the different answers to this... What I do is add a few links a week and use GOOD keywords in the link back... That helps me enough... Why should I get 1,000,000 backlinks? Most sites have like 25,000.... that are #1... - Chris
From what I understand, google pays attention to the speed at which you acquire links. Go slow and steady to start, then ramp it up as your site gets more popular.
Google penalizes you if you do too much link exchange and other automatic link exhchange but i try automatic links exchange for my first site it got me a page rank of 2 i was lucky google didn't catch me doing that though.
I don't think you'll get a penalty, but the value of those links will be filtered somehow. You might also lose value for some of your other links. I think Google looks for unusual patterns in your link building. So if you gradually get more links, it might not be abnormal to receive something like 1,000 links in a day. However, if you usually receive 1 or 2 links a week and then 1,000 in a day, this shows up as a huge spike in your link building. Google might have some filter that "flattens" those spikes by decreasing the value of those links.
Then they have even less value. Google also has a filter for too many links from the same site. These filters all decrease the value of links when they detect something abnormal.
i have hear that more than 0.1 million link one day that is day to earthquake in china more than 80 000 person was killed .all website link your website and donate money.
