I found this while perusing another blog, and since it's so similar to stuff that I have dealt with in the past, I thought it was worth a giggle for y'all. This "nice man" was concerned about some spam he got, so he decided to call in to the hosting company he felt was responsible.
Note: I am making no judgments about whether or not the spam was really originating from the company in question, just giggling at the voicemail and the blog post.
Note 2: Please take the warning about language seriously. This "nice man" has a worse potty mouth than me.
Note 3: Doesn't the bleeping make you giggle? Cheap headphones as bleeping mechanisms FTW!
