I'm using an unmodified version of Flickr Gallery on my WordPress 3.2.1 site. The Google bot sees a spammy title for my blog when Flickr Gallery is enabled, but not when this plugin is disabled.
I verified this on my site with the following code snippet. Note that as I write this the plugin is disabled so my blog title appears correctly. With the plugin enabled I see "Buy (name of drug) Online No Prescription" as the title of my blog.
curl -A 'Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)' 'http://weill.org' | less
Has this happened with anyone else? Google was kind enough to alert me to a "notice of suspected hacking" when the above occurred, but after fixing many such "hacks" I was able to isolate the issue to this plugin.
