When someone repeats an argument that has been proven false /badly argued many times before, but keeps repeating it in hopes of drowning out opposition or derailing a thread. Yet not disruptive enough to get banned on forums, as it wraps itself in non-hostile, nicely written sentences.
How exactly do moderators deal with this kind of behaviour?
Sea lioning is pretending to be interested in a reasonable discussion when you’re really looking to wind someone up until they lose their temper.
Maybe OP was meta-posting
