/**
This script removes tweets that mention more than x number of
trending topics (spam!) from search.twitter.com. I borrowed heavily 
from the script twitterRemoveTweetsWithKeywords, found here:
http://userscripts.org/scripts/show/52543

Customize below!

/*-----------CUSTOMIZE------------*/

// trendingTopicLimit - the number of trending topics you want to
// allow in a tweet. With 2 set, a tweet that includes trending
// topics #iranelection and #neda will show, but one that includes
// #iranelection, #neda, and Michael Jackson will be hidden.
// Set it to 0 and all tweets on a trending topics page will be spam ;)

// showSpamImages - set to true if you want to see the number of
// spam tweets that were removed. X number of spam icons will show
// up at the bottom of the page and you can expand to view them.
// Set to false if you just want to get rid of them and don't care
// how many tweets were removed.
