Yes, there seems to be something else that is wrong with the Google index as some pages from the cakecentral.com domain show up with content from beerby - this has been noted by someone in this thread and I could just reproduce it.
On the other hand, we can never be sure if pages exist or where they are on the web that link to our pages with a certain anchor text. The link: operator is broken since a long time and shows only a small subset of the pages linking to the page in question if anything at all.
A more complete list of links can be found in the Google Webmaster Tools, but this is also never 100% complete or up to date. And we can use the Site Explorer to get on the quest to find a certain link:
siteexplorer is more than useless, and the google link: operator is crippled, but for a link bomb you need quite some links with the exact matching linktext, but a simple search for ["cake central" beerby] does not show anything. (and other queries with the link: inanchor: oprators, too) so that it can be relativly safely assumed that it is not a link bomb (in a link bomb you always find some of the links)
or lets phrase it like this
there is absence of evidence that it was a link bomb
These terms only appear in links pointing to this page: cake central
Looks like the good old Google bombs still work :) http://en.wikipedia.org/wiki/Google_bomb
