Spam I'm getting this week

It's a new, friendlier, done in confidence, spam that has been arriving in my inbox this week. I must have received half a dozen of these emails this week. My real question is, why can't the base network filter geeks prevent this junk from getting through and into the system?

Listen, I am not sure whether you got my first message or not. I am sort of concerned. People are making me feel ncomfortable and I don't like being in the middle. Some of the staff are spreading rude jokes behind your back about your weight. I personally have no problem with you being you.
Please don't come back at me for informing. I just wish to help if anything. I thought about mentioning it to a boss but then to have something like this explode is silly and embarassing for everyone involved, including you being the center of attention. If you really want to make somewhat of a difference, I know my cousin and friend both used this and it worked very well for them. They grabbed it off the internet to keep a low profile & stay confidential. This was the site they got it from, if this helps any.

Again, I don't like people insulting others behind their backs. I am only trying to help. Which I hope I am.
Thanks for at least listening & I hope I am not out of line by writing this.
I am only trying to help.
