"To some observers this activity can be very clearly seen. And if they try to counter-balance this activity by posting messages of comment or asking questions for verification of dubious claims, they are immediately disparaged, insulted, attacked, or falsely accused of wrong doing in order to undermine their credibility. In this way this treacherous fraud is allowed to continue and flourish. If they should persist and further complain or otherwise resist these attacks their posts are then deleted, one after another, under the ruse of being 'off topic', or several other feeble and superficial excuses. And complaining to the web site management does nothing more that cause them to further facilitate this fraud by actually censuring or banning the complainants. And ultimately banning them from the very forums where the activity is happening. In this way the complainers are silenced while the success of the perpetrators is guaranteed."
I think some of us here experienced this there.
