Filter out suicide events

[elliotblackburn]

It looks like quite a few suicides are coming through on the scraper, it would be a good idea to have some sort of content filter if possible that attempts to block the posting of suicide reports. They don't represent the issue correctly and so it would be useful to not add them to the posts.

This is the number 1 back lash we seem to be getting right now so it's worth fixing in the next few days.
