A member that goes against the doctrines by the GB and are subsequently disfellowshipped for "apostasy" although they are not rebelling against God or Scripture but rather the man-made doctrine interpretations, these type of "apostates" are usually very honest and open about their plight. This is the first example.
On the other hand you have the type of member who gets disfellowshipped due to practices condemned by Scripture, let me emphasize, practices that are clearly prohibited in Scripture. These members start off their disfellowshipped life being angry, resentful, and even vengeful perhaps because they were caught, are embarrassed, marriage in trouble, family in shambles, or perhaps for how Elders sometimes will deal harshly with them instead of trying to comfort them and admonish them like the lost lamb that they are. This is the second example.
The third example is that of members that are disfellowshipped for clearly going against Scripture in believing in things like Hell, Trinity, etc. These members usually will never return to the Organization and almost immediately they will commence posting and openly going against what Scripture is clear on. Once this threshold is crossed, they become very adamant about their position and many times they will start their own church or group.
The fourth and final example is of members who realize that they have been misled by the GB, start to fade quietly, and sometimes move away in order to successfully fade with their entire family and social circle intact.
It is the second and third examples of those that I have found to sometimes flat out lie or stretch the truth out a bit. Their reasons are obvious; trying to add to their membership roles, and trying to undermine the organization that caught them red-handed but crossing over into actual "apostasy".
The first and second examples will usually remain honest while sometimes extremely critical of the organization but nevertheless they remain honest.
All of these four examples are members who are lumped into one group as "apostates" by the organization for going against them in some form or another.
The second example is the classic "apostate" example. While the third example can evolve into other forms that are not Godly such as atheism. Once this happens they will turn on God and start to berate Biblical teachings even lying about Scripture.
