One of the things John Reese suggests in the backlink building lesson is that a new site should only build 1 link a day for the first couple weeks and then to increase it to "maybee 2 or 3 a day".
What a load of cobblers....
While building hundreds of links in a day will guarantee a ban anyone who spent the day building backlinks for their site can easily manage 15+ quality backlinks.
At the end of the day if your backlinking is done naturally you have nothing to worry about.
Sometimes i wonder what these so called 'Gurus' intention's are by feeding people with junk information.
