Frustration has nothing to do with it, spreading false doctrine does (2 Tim 4:3-4; 2 Th 2:8-12, etc.). What you refer to as frustration is probably (at least from my part and I am sure Pilgrim's as well) the knowledge that sooner or later you will have to confront the sin and the sinner, which is not fun, but necessary. Please look at Speratus' 767 posts for yourself. In many, if not most, of them you will not only find error, but the continuous defense and teaching of “false doctrine” that is destructive to the Christian faith. His defense of error is “normally” not with Scripture, but with a certain “teachings” and other “unsupported” comments that he purports as truth.

As you know “generally” a heretic/heresy (there are different types in Scripture: (1) Acts 15:5; which simply means a party or sect, or what we call a denomination, (2) 1 Cor 11:19; “internal” groups which threaten the harmony and unity of the church, (3) 2 Pet 2:1, damnable heresies, etc.) is a person who dissents from the doctrine of an established church, or in this case an established forum. This forum has specific guidelines that emphatically state it is Reformed—which Speratus knows (Forum Guidelines)! Though this forum is very gracious and allows the discussion of other views, it does not allow the propagation (teaching) of “false doctrine,” which Speratus continually attempts to spread. This dissention causes disunity and spreads a false gospel.

Many attempt to defend such individuals because they think they are being mistreated and can be evangelized. While I agree that some initial mercy should be displayed to bring them to repentance, the Scripture says that they should be rejected after the 1st and 2nd admonition (Tit 3:9-11). Speratus has been warned before.
