Most of them are still around. The Christmas picture had even more artists who ahd disappeared from the fandom. In contrast, this image had more artists who are regular, came back not too long ago, or at least made an account on fluffycommunity. The immediate exceptions I can think of are Waggytail, Squeakyfriend, Fosterfluffy, Marcusmaximus and Bluefluff, but they’re all hugbox artists who I hope will return to the fluffy pony fandom some day.
