Just like many said don't do more then 10-20 Links per a day. My method is to create loads of content for the site first, wait a couple of weeks before start linkbuilding.
The problem is not only how many links as you may get 100 links but google may yet index only 10 fr that day. So I guess this makes my question more complicated. I can understand women but I can't understand Google.
It depends on the quality if Backlinks. For example 100 Links from PR 0 per day = It is ok But 100 Links from PR 6 per day = It is very danger 100 Links from PR 0 - 10 Links from PR 6 = It is ok per day.
Somehow I feel the age of your website also has some influence towards number of links per day. Of course those which are around for sometime would not raise suspicion with sudden increase or surge in number of backlinks per day.
Just think as if you are google, first of all you shouldn't understimate SE, they have great experience and can easily understand if you are using underhanded methods, if some people say: "NO THEY DON'T!" it just means that they slipped through there hands, after all google isn't omnipotent, so my advise would be something like that: be as natural as you can be, in general, new sites get around 20links a month, 30 in the second month, 50 in the third and so on, be modest and it will bear some fruits.
As many backlinks as you can but beware about one thing: try to add them constantly not all in one day and then nothing. If you do that, you can be marked as spammer (eq. if you get 1000 backlinks in one day, then a few days you get 0-10 links and then you have another 1000 backlins in one day... it's not good for your serps ).
