There is no so called maximum links that u can build per day, but if u build 500 the first day, then zero the next, well, u know how it suspicious it seems!
It can be 25 or 100.. but you have to make sure that you are getting it every day in the correct time intervals (may be per day or per week). However, If it is a new site, it is more adviseable to got with 5-10 links per day, instead of more than that....
I am totally agree with mate. You can create as many as you want but you have to generate quality backlink for your site. Means you have to more focus on do follow backlink for your site. Else it is not useful.
