It's 2020, so all the older appreciation threads are closed.

It's fine to start new ones for your favorite characters, provided it hasn't been done already.

The titles should just be the character name 2020 and appreciation thread. You don't need to expand the thread names.

It's okay to go with the alter ego and the secret identity, especially when multiple characters have taken a moniker (Scarlet Spider, Green Goblin, Venom, etc.)

So "Harry Osborn Green Goblin 2020 Appreciation Thread" is fine.

"The American Son With the Legacy of Evil; Spider-Man's Greatest Frenemy Harry Osborn Green Goblin 2020 Appreciation Thread" would be inconsistent with other appreciation thread titles.
