I just post a lot on a famous blog that I'm following and on digitalpoint. I don't know how did I get the rest. My blog is just just more than 2 weeks old!
it is probably if you have a top commentator spot on a blog with lots and lots of pages... that is one way to get a lot of backlinks quickly... but it won't help PR much because they are mostly all from same domain...
I had something similar, I used to post stories to Digg, Su, etc. and in 2 months, the pagerank update came and it jumped from 0 to 2. I think that it just takes some work from us, submtting our sites here and there, on signature links, on blog comments, and on social bookmarking then things will start to look fine after 2months or so. But you got them in 2weeks which is quite the Wow to me, how did you achieve that. If you'd like to keep information private though, no problem, I wish you best of luck in your online business.
Yeah, and they'll go away after the comments roll off as new ones are made (unless you keep up the comments all the time). If you're not buying or selling links, or participating in 'link schemes,' I wouldn't worry about it. And you won't get banned, but you might get penalized.
Whether your site gets banned or penalized will have more to do with where these links are coming from than how many there are. None of us can say. What you may encounter is a temporary "sandbox" that will keep you from ranking well for particular terms for a brief period. This seems to be an automatic filter against new sites which may be violating guidelines. Your site may also get pegged for manual review. Unless you are using BH techniques, a ban isn't too likely, but it you have dodgy code you may wish to get rid of it. Apart from that, don't worry about it...sudden links occur all the time and it's usually legitimate.
naaahhh imagine having 2000 posts in DP and not having anything in signature.. suddenly you plan to include your link in sig. You will have 2000 back links soon and that does not mean you get de-indexed!!
