Spam + Donation = Spamation? Is it acceptable?

I got this interesting spam in my comments today:

Please, do not delete the given message. Money obtained from spam will go to the help hungry to children ugandf

What do I do?

I figured someone who can stoop so low as to spam is not likely to donate his ill-gotten wealth. Secondly there are better ways to ask for donation than to spam. Thirdly I don’t believe ill-gotten wealth can ultimately be beneficial to anybody. Not to mention the spammer doesn’t even know how to spell Uganda! With all these in mind I deleted it.

What would you have done and why?
