It's called citing sources. You've posted 2,087 times and only 56 of those posts include "http"[1], which is a measly 2.7%. In comparison, I've posted 556 times and 205 of my posts include "http", which is 36.9%. The problem isn't sealioning; it's that you're either lazy or you just make things up. And given that you're not too lazy to reply to a request for a source without actually providing a source, it's reasonable to assume you might be making shit up.
