Lately LH has been experiencing a lot of spam comments. These are
usually generated from specific users. Ryan Bigg was nice enough to
write a script using mechanize to delete comments from specific users.
I use it sometimes to delete the spam and in case I can't get to it,
please do use it to get rid of the spam comments.
The script --> https://gist.github.com/53f8a67c0a8854b45a2c
Also I had opened a ticket (now closed) on LH regarding the spam.
Maybe they need more pestering to add more protection! The ticket

P.S It goes without saying that you need to be careful with the user
id's otherwise legitimate comments might get deleted! And also you
need the authorization on Rails LH to delete comments for this script
