I've been reading up on the sandbox theory, one of the suggestions as to what triggers this feature is if a site gains an excessive amount of back links too quickly.
My problem with this is that I attended the SES conference in June this year, and a speaker from Google said that it was not possible to damage another companies rankings, for example by linking to them from blacklisted/spam sites.
So my question is, what is stopping a company from hindering a competitor's new website by linking to them from let's say every one of it's 1000 pages of it's own website.
Obviously it's not a great long term strategy, but seems to be a flaw in that part of the theory.
I'd be interested in your comments.
