Multiple things in this suggestion.
Note to mods: There is a suggestion similar already in the forums, but this is going to differ and include something else.

1. Special Lionesses being sent to users who haven't rolled in some time.

A user should have rolled within a certain time before the drawing for their entry to be valid on the day of drawing.
If they haven't rolled within a few days before the special lioness is drawn, it should be re-rolled automatically.
Or perhaps to make it more fair, they have to click a confirmation within a few hours two months roughly of it drawing it, otherwise it gets re-rolled to a new winner.

2. Older Special Lioness designs being reused

There are so many unused, untouched RLs tucked on banned or dead accounts. These designs should be reused if they haven't rolled within 1-2 years of winning the RL to prevent designs and marking slots from dying off.

Maybe a certain age restriction before their design can be used again, like if the lioness is older than 5, for example, their design can't be reused. Even if on a banned/dead account.

And a restriction for those accounts that are just dead and might make a return at some point, though we won't know.
