One story on a blog by a discredited ex-broker does not prove anything.
True.
However, try a Google on "Harry Markopolos". You'll get stories like this; How Bad Did the SEC Blow the Madoff Ponzi Scheme
FWIW, Markopolos is a guy who was a fraud investigator and worked for a rival firm and wrote to the SEC on more than one occasion with allegations about Madoff's caper as far back as 1999. They were never investigated. OK, you can say that the SEC gets lots of complaints by disgruntled investors but this story about Madoff is not new.
There have been questions out there about his methods for some time.
P.S.
You owe all these good folks to whom you have so rude an apology.
