hoogle needs to be less botcrawlable #442
Description
In particular, bots and crawlers (which the ai bubble has thrown up in great numbers) seem to get lost in a maze of links when they search for something like "id" then just keep exploring all of the is:[pkg] left hand links. adding nofollow might help, but these are lawless bots and i doubt it.
suggest that if there is is:[pkg] in the query string already, then no further left hand package links be shown, so there's not a branching maze path that traps bots.
