I recall that I had suggested to infofront that he (infofront) should delete some of his (roach's) posts once in a while, just to discourage a certain amount of the off-topicness and obvious desires to divert us from making more meaningful and substantial posts about bitcoin. Can't know, for sure, unless infofront discloses regarding whether he is deleting some of roach's posts from time to time.
