A simple matter of going through my extremely large spam folder and finding one that's reply-to-able. I'm not sure if the task requires the spammer to respond, but hey. Here is the log:

Spammer:

"Hello,
We have brand new models of those w4tches from 2008:
- r0lex
- cart1er
- ch0pard
- iWC
- hubl0t
- bre1tling
- patek phil1ppe
- tag heu3r
and much more. Average price of those quality w4tches is $229."

I thought it odd that the spam had no attachments or web links of any kind, so thought writing back asking for more details would prove fruitful.

Me:

"00h, f4nt4st1c. 1'v3 4lw4ys w4nt3d 4 br31tl1ng. H3y, c4n y0u
und3rst4nd th1s? Y0u n3v3r s41d h0w 1 c0uld g3t s0m3 0f th3s3
w0nd3rful w4tch3s, 1'm 1nt3r3st3d n0w! Wr1t3 b4ck 4nd t3ll m3 m0r3!"

(Roughly translated: "Ooh, fantastic. i've always wanted a bre1tling. Hey, can you understand this? You never said how I could get some of these wonderful watching, i'm interested now! Write back and tell me more!")

I'll update if I get a response, but I couldn't see anywhere in the task that said the spammer had to respond.. Mwahah.
