Vonage has had a pretty bad couple of months.

There was the botched IPO leading to plenty of pissed off shareholder customers (myself incuded), combined with a few new patent lawsuits. The stock hasn't done well at all -- something many predicted well before the IPO in the first place. Now, spyware researcher Ben Edelman has released his latest article, noting that Vonage ads seem to show up in an awful lot of spyware -- including every one of the major spyware providers. And you wondered why the customer acquisition costs were so high? Now you know that a large chunk of that money was going directly into the bank accounts of some awfully questionable companies.
