I didn't have a word for this before. Now I do.

Sealioning is the technique of a bad faith inauthentic "polite" timesuck asstroll and/or a shill with an agenda, paid or not, ignorant or intentional, who is determined to never learn anything, tie you up in perpetual circular logic argument knots, never grow, waste time, waste resources, waste motivation, and is determined to muddy up forums and/or harm good sites. First and always, never budging, never growing, never evolving, from their cemented positions they start arguments and only select and cite the information they need to waste your time. They deflect, squirm, evade, distract, change topic, spin, lie, and say they will look at your counter-information and never do. Inauthentic through and through. If this isn't downward bad faith I don't know what is.
