Moving the goalposts is an informal fallacy in which evidence presented in response to a specific claim is dismissed and some other (often greater) evidence is demanded. That is, after an attempt has been made to score a goal, the goalposts are moved to exclude the attempt. The problem with changing the rules of the game is that the meaning of the result is changed, too.
Sealioning (also sea-lioning and sea lioning) is a type of trolling or harassment that consists of pursuing people with relentless requests for evidence, often tangential or previously addressed, while maintaining a pretense of civility and sincerity (“I’m just trying to have a debate”), and feigning ignorance of the subject matter. It may take the form of “incessant, bad-faith invitations to engage in debate”, and has been likened to a denial-of-service attack targeted at human beings. The term originated with a 2014 strip of the webcomic Wondermark by David Malki, which The Independent called “the most apt description of Twitter you’ll ever see”.

Be specific what goal posts you claim to have been moved. I’ll wait.
