In a flip of the words, look at the hit count for mentions of suicide on MySpace:
Google shows 29.1 million pages for site:myspace.com
Google shows 1.86 million of those include the word “suicide”
If you remove “goth” you still get 1.75 million, so that’s not it.
Adding “depressed” didn’t do much to the count (62,000), nor really did “depression“
