In particular, this thread about Atebus Revolution Masquerade 2020 that was created December 2019 is less than fifteen months old: https://subeta.net/forums.php/read/906809 It got put into the Archived subsection of Suggestions, and then locked. This is a weird place for it.
Did the necro bot app that automatically locks things for all y'all have put it there? Because it's still in play, IMO. It's still useful as a source of ideas for us for things from this year that we didn't get but still want for 2021, and as a springboard for new ideas.
Yes, I couldn't find the thread at first because I didn't know it had been moved since most of the other suggestion threads haven't been moved to the Archived Suggestions forum, so I thought that the person who had started the thread had ended up on my block list.
