Probably, I think that because the chances that those 300 links being mostly quality links is very slim. You don't want to make your site look like a spam site; however, if you can get 300 quality links per day then I don't see why not. Large project websites do it all the time, upon launching a new website you witness a great amount of links starting to appear to that site.
Yes if you are new, you don't want to built links to quickly. It's quality links rather than quantity.
And I'm sure that those 300 links, most of them are coming from low quality site. Don't be so too fast in building linsk for your site especially if those are crap links.
It depends on the age of your site and the quality of the links. If you have an old site and the links are good ones then there won't be a problem.
If a big corporation launches a new PR campaign they go from 0 to 100,000 links in a day - and it doesn't hurt them. The key here is where you get those links from. If Google see it's spreading virally I'm sure they are smart enough to not penalize you. If you, however, get 300 links from automated spam blogs I'm pretty sure Google will pick up on that too and give you a good spanking.
Don't listen to all these people on that forum, mostly know nothing about 300 links a day cause they never had such sum. From a person who has experience with getting that much by original sources i can tell you it only brought good.
In my experience, as long as they're to a number of pages, from a number of domains, and using a variety of keywords (and even some with no keywords - "http://website.com") you should be okay. If you're using the same keywords all the time, or linking to the same pages all the time, then its more likely that the algorithm will pick up on this. I've had the algorithm catch me before. The site dropped out of ranking for the keyword that I was targeting, but otherwise was unaffected (still ranked well for a number of other keywords). It took me about 2 months to spread out links & keywords to other pages, and then the site recovered. Good luck, and let us know how it goes.
Do it & you'll get Google sand-boxed or banned altogether. Don't do it. Your site isn't Google, MSN, etc..
if your website it's a new one, then try to keep it under 100, if your site it's a bit older, then try not to push it over 150/day good luck!
Mostly importantly, build links pointing to your site, slowly and steadily but also on high PR do-follow blogs. This will build up your PR quickly and your rankings in the SERPs..
