I don't think this is a good idea... about a decade ago... as a research project I ran honeypot farm of 13 machines to learn more about malware. The honeypot machines were autonomously surfing the net, parsing the DOM and choosing random links. I ran them in a sandbox and was getting weekly malware hits.
Much to my surprise... most of the malware was coming over advertisement networks on shady websites.
