Yes, it's possible.

OK, the pokeball mystery is partially solved.

Solved part: Website Contributors were missing their pokeballs, but I've already fixed that problem. (If I've missed anyone, please let me know.)

Unsolved part: pokeballs don't show for mods/admins/supermods who have edited our custom titles. I haven't found a way to fix that, sorry. But if you're a mod or supermod and want your pokeballs to show on your profile, let me know and I'll paste the HTML into your user title. It's the closest thing I can do.
