I'm not a fan of megathreads. Imo, it'd be best to keep the oldest post that links to a non-clickbait article, and if someone posts an article covering nearly the same content, remove/lock it and link to the other post.
EDIT: If it's about an ongoing topic that wouldn't be resolved for more than a few days, then a megathread might be appropriate.
Glad I can use this as my main instance again. Love the transparency of the mod team even if I don't always agree with the decisions.
