I've been getting a ton of spam on GMail lately that falls into two categories: Russian-language spam, and another spam with several variations, of the form:
- Hello! I am bored this evening. I am nice girl that would like to chat with you
- Hello! I am bored this morning. (etc)
- Hello! I am tired this evening. (etc)
- Hello! I am tired this morning. (etc)
- And so forth...

You can also test this against your mailbox in general by putting that exact text in the search box in gmail, and if you want it to search everything, add a space and then in:anywhere.
If you have any other filtering tips, post a comment.
