Your question is confusing because:

• I rarely see a meme on Lemmy.
• The term frontpage isn't common, or it's from a specific UI on Lemmy.
• There isn't a frontpage channel used to curate posts.

Can you put an edit at the bottom of this, something like:

""" Edit: When I said frontpage, I mean the page that initially loads, the one that shows your subscribed channels or if you have none "All". """
