Here's one.
I haven't made any purchases at all here..nothing, nada, in about seven years, but I got an email in my Renderosiy Site Mail.
Honestly, I don't know what "Site Mail" is, or how it differs from an IM, but nevertheless, it's there:

From Miss Christelle Adams,

 

christelleadams008@yahoo.com  christelleadams0/0/8/at/yahoo/dot/com

 

This letter may come to you as a surprise due to the fact that we have not yet met,but it should'nt,since we are determined to get what rightly belongs to us anyhow,but soon when every thing goes according to plan.The message could be strange but reality will definitely dawn on you, if you pay some attention to it's content. I would'nt have notified you but for the sake of your integrity and goodwill.Please accept my sincere apologies.

 

In bringing this message to you, I have to say that I have no intentions of causing you any personal pains or discomfort.My name is Christelle Adams ,23 years of age,living in the company of my junior brother a native of Dabou in Cote D'ivoire.

SNIP

And, of course, it continues along that standard scam.

Note that this was only here, on this site, and was not forwarded to my regular email addy I have registered here.
Note also that I do not have a paid Renderosity email account.

Two questions I have:

1. How did I get that here, but not in my normal email?
2. Why is it an email, and not an IM?

I figure if I'm getting such stuff, alot of other, more active members here must be, too. I'd repeat, i have boght nothing from the store since 2000 or so, and nothing, ever, with the email address I have now. Totally different ISP.
