Fundamental independent churches practice it, and then we hear tales of the horror of anectdotal Baptist churches, somewhere in the south/midwest actually discipling someone and the indignant lawsuits that result.
There is a reason that Christ said he'll purify the church and start with the pastors and work His way down. People are sinners. We see it in the bible, time after time, the Kings sin, Kohenim sin, the Levites sin, everyone can sin. It seems to be a condition of mankind.
INDEED.
WELL PUT.
