Apparently this group in Russia:
a@softsearch.ru
and probably related are trying to spam people's reputation. Feel free to email them from a throw away email account and tell them to stop their nonsense.
I also saw a ton of spam about an investor acquaintance of mine - a nasty insulting page repeated over and over and over again on the net.
I think Google needs to look into this repetitive harmful content. It is obviously spam by someone who wants someone else to take a fall.
