Um… I just came across this thread and I think it has nothing to do with Zbrush. 
Haha probably not 
Thanks for catching this. We nail most spam before it ever even appears on the forum, but every now and then something gets missed.
In the future, the best and fastest way to report it if you see it is to click the Caution sign icon in the lower left of the post. This lets you notify the moderating staff immediately so that we can get rid of it.
Sorry, I should have guessed that posting a link here makes even more people click on it just out of curiosity.
Next time I`ll report things of that nature via the caution sign icon.
You said you nail the most spam before it ever even appears on the forum and in fact, it was the very first time that I saw such a post here.
Good job Zpam hunters! ;D
