The APS lists 'Disciplinary Actions' on the website for years 1995 through 2106. It is a listing of suspended/reprimanded and expelled American Philatelic Society members. When I compiles the list, I noted an interesting trend and would like to hear opinions on what others think what explain it.
There has been a clear drop off in the number of members who are listed each year. During the same time period there was a corresponding drop in membership but this does not seem to track well with this trend. The year 1999 saw the largest number of actions with 40, last year was the lowest with just 1, this year there have been just 2. As the chart below shows there has been a large trending decline in the number of disciplinary actions.

I somehow doubt that human nature has changed over this time period and would expect the number of annual actions to be roughly the same as a percentage of total members. In fact, I expected a possible increase in this time period since the number of members who have turned into 'dealers' by listing online has certainly increased over the same time period; giving more opportunity for ethical breeches. A cynical opinion might assume that APS has lowered the ethical standards so not to add to the declining membership ranks (hopefully this is not the case).
Does anyone have a more intimate knowledge of any changes in how Disciplinary Actions may have were tallied during this time period and could explain this trend?
Does anyone know if this list published on the website is complete for these years?
Do staff changes impact the number of Disciplinary Actions?
Anyone have other opinion(s) on what we are seeing here?
