Why is the Crooks, Frauds, Liars, and Banksters board closed to posting...
Because it's not open to posting?
Seriously, I took a quick look at that board a day or two ago and was appalled, yes, appalled at the total disregard for iHub's rules of conduct exhibited by several posters thereto, present company included. So, I closed the board to stop all such ill-conceived postings, and after removing any number of profanity-laden posts decided that the entire board should probably be wiped out and egregious violators should be considered for termination.
Alas, I had forgot about part two until you brought it to my attention.
