There are many threads about this topic, I know. Also there are a lot of opinions. Some say it is OK to build a lot of links in a short period of time, and others say no.
The main reason - at least in the past - why people said it's OK was that if it could harm you site then you could harm other sites on purpose as well (negative SEO) and as long as I could see it seemed to be true(it was OK).
But, after recent changes in G, I hear a lot about the possibility of negative SEO and a site having disappeared from SERPs after blasting the site. Links really have to look natural etc. etc.
Then at this point how many links per day (or per week, or any period of time) do you think is considered appropriate by Google? Did recent changes in Google change your thoughts on this?
(I'm not talking about "blasting" the site by thousands of links, I'm talking about more like, say, 100 links in a week is OK or not.)
