Sea Lioning
What it is
A bad-faith harassment technique disguised as polite, persistent requests for evidence, explanation, or debate that exhaust the target.
How it works
Real-world examples
- •Replying to every social media post with "Can you provide a source for that?" regardless of how well-established the claim is.
- •"I'm just trying to have a civil conversation" while demanding hours of unpaid educational labor.
- •Concern-trolling academics by endlessly questioning their methodology without engaging with findings.
Ethical guidelines
- ●Good-faith inquiry is finite and responds to answers. Sea lioning is infinite and ignores them.
- ●The right to ask questions does not entitle you to unlimited access to someone's time and energy.
- ●Weaponizing civility norms to harass is still harassment.
How to defend against it
- ►Set a limit: provide one thoughtful response with sources, then disengage if the pattern continues.
- ►Recognize the pattern: if answering questions generates only more questions, never satisfaction, it's sea lioning.
- ►You are not obligated to educate every person who demands your time — block freely.
From the Defense Playbook
Before taking an online account's word, or taking a crowd of accounts as public opinion, spend a minute on the profile itself: its age, history, posting rhythm, network, and photo, which together show whether you are looking at a person, a persona, or a coordinated operation.
When someone treats every reason you give as an opening for negotiation, stop supplying reasons: state your decision once and decline to justify, argue, defend, or explain it; this is folk practice from support-group culture rather than a tested technique.
Calmly repeat the same short statement of what you want or will not do, in the same words and tone, as many times as it takes, without being drawn into answering each new argument.
Answer an intrusive, oddly specific, or out-of-place question with a friendly question of your own about its purpose, which buys time, reveals intent, and breaks the reflex to answer simply because you were asked.
When faced with a pile of arguments, ask the other side to name their single best one, or choose it yourself, and examine that one thoroughly, instead of chasing every point or knocking down only the weakest.
When a new topic is introduced in the middle of an unresolved one, acknowledge it, write it down as something to come back to, and return to the original point, so that diversions neither derail the discussion nor go unanswered.
Before arguing over who is right, ask what observation would count against the claim, and agree on it in advance; a claim that no possible evidence could count against is not being offered as a claim about the world.
Every playbook entry states how strong its evidence is and when not to use it. Browse the full playbook.
