I'm seeing a disturbing increase in spam posts promoting personal enhancement products such as male enhancement, hair care, dieting, brain enhancement, and other similar products. The following list (all links 10k only) were some of the more recent I have identified:

- http://superuser.com/q/935763
- http://superuser.com/a/935755
- http://superuser.com/a/934843
- http://superuser.com/q/934826
- http://superuser.com/q/934401
- http://superuser.com/q/931828
- http://superuser.com/q/928448
- http://superuser.com/q/916065

These kinds of spam are coming up more often than ever and I have been unable to track them down to any common source. WHOIS and reverse DNS lookups of the domains (via [VirusTotal][1]) listed in the spam posts have not found any obvious pattern. Is anyone here able to trace these posts to some common source? (We might need a [Stack Exchange Community Manager][2] here.)
