A subreddit I help moderate sometimes gets a sudden wave of comments on an old or controversial post. The activity might come from a link shared elsewhere, but it is hard to tell whether that means people are coordinating a raid or simply reacting to a post that gained attention.
When assessing a Reddit traffic spike, what patterns are genuinely useful to moderators—account age, comment timing, referral context, or something else? I’d like to avoid treating ordinary newcomers as rule-breakers while still responding quickly if a thread is being targeted.
