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
