By calling someone a "moron" it begs the question and by definition is an attempt to discredit, then you state your reason or rebuttal which makes it an ad hominem or at least an informal fallacy. It's not necessary to become emotional about how someone perceives your satire as not funny and then mocks this satire with a hashtag. Perhaps you see the irony in being upset about how someone mocks your mockery. I'm actually quite pleased at how oddly funny this has become.
