Isn't it a bit against the spirit of Secret Santa to reveal everyone's names? Half the fun is trying to figure out who did what until/unless they decide to reveal themselves.
The “rules” of Secret Santa vary by community. Pixelation’s tradition is to reveal all of the gift givers’ names, but only on Christmas Day. Before that, it’s a total secret what everyone is working on and who it’s for.

Since art takes a lot of personal time and effort to create, many art communities operate their Secret Santas this way. Those who didn’t participate and are browsing through the gifts can discover artists they may not have known about before, which is always great!
