I've even been seeing the old "could you kindly (deliberately obtuse bad-faith request to "prove" something "objectively" where any evidence given is a "biased" source or "has a narrative")" sea lioning tactic. They even do the smug "I'll wait" follow-up line.

One even asked me to objectively prove that they were sea lioning and threw a slang dictionary at me (that for some reason only included a weird and obscure "stalker" definition and not the bad faith evidence demands) in a way that was sea lioning the idea of sea lioning.
