If you look around this wiki, you'll see that many articles state whether or not an individual is currently a member and currently active or inactive. However, I think that this data should be removed from articles.
The thing is, it is not important if an individual is currently a member or not; thus, adding this information violates our Manual of Style and is completely unnecessary. Anytime that it may be useful to point out, this information can just be added to the body of the article.
In addition, whether an individual is active or inactive is often subject to your opinion and may not reflect other people's opinions. It would be better if it were not included in encyclopedic articles at all.
Finally, both of these pieces of information change often, so articles can quickly become out of date. I think it's time we get rid of this information from articles.
