There has been a little change, which I observed from the merit source data board. We previously had about 109 merit sources, and currently the number has been reduced to 88, and the total number of Smerits by source is down to 31318 from 32990. A lot of inactive merit sources have been removed, and from the announcement on Meta, it appears that a few merit sources have also been added. This could be what the admin was doing the day merit sources were experiencing a bug on their merit send page (negative Smerit).
The decision to remove inactive merit sources is really great. Even some new merit sources have been added which is definitely good news. But the number of merit sources has been reduced which is definitely bad news. Maybe it would have been a good decision to replace the inactive merit sources with some new active and sensible members as merit sources. Because the forum lacks merit sources who will read the posts regularly and give merit to the deserving posters. Although there is an alternative thread for this, I think it would be better for active merit sources to find the posts and give merit than to report the posts.
