I could not tell you how many camps there are. There are those who gather around the colleges, but there are others who don't follow a college or follow multiple colleges. There are some who choose to go solo others that form informal associations. I'm part of an IFB church for now but I don't really identify as IFB. You will notice the verse I quoted below does not come from the KJV.
I don't claim to be wise but the God of the Bible is and here's what He has to say about slanderers:
Romans 1:29-31
29 being filled with all unrighteousness, wickedness, greed, evil; full of envy, murder, strife, deceit, malice; they are gossips, 30 slanderers, haters of God, insolent, arrogant, boastful, inventors of evil, disobedient to parents, 31 without understanding, untrustworthy, unloving, unmerciful;
