For anyone wondering “how people find these threads” it’s really quite simple.If what they were looking for led them to a thread in off-topic, I'm wondering why they even looked it up in the first place.
They probably were interested in a topic and decided to search for it rather than posting a new thread using osu’s Search tool.
People often say don’t create new threads if one exists and yet to not necro a thread. That would mean though that no old topic can ever be discussed again if you followed both rules.
Because a lot of the necroposts seem to be on old shitposts that are "neither funny nor interesting".
