Spam Filter Creators Appreciation

It amazes me that there really must be a lot of people out there who open their emails with subject headings full of misspelled, suggestive words. I thought about copying some of the more creative ones here but don't want my blog to be marked as spam, but I know you all know what I mean.

I figure people would stop sending them if they didn't have a decent rate of return, right? Sure, some are sent by strange people who either are trying to be funny or who are just experimenting - but I assume most spam emails do have some sort of benefit to the sender and that benefit must be enough that they keep sending them, otherwise why bother?

This is all in my mind because I just spent some time in my filtered inbox - I try to check it every few days to make sure something important doesn't accidentally end up in there, and I suddenly found myself admiring the people who set up the filter parameters, because really, they do a very good job. It's very rare that I get a spam message in my regular email inbox, and it's even more rare that a real message gets filtered out.

Which is pretty impressive, you gotta admit.
