Typing "I liked my own comment" as your comment automatically makes you cringe.

 Pretty sure people are doing it because I exist in the comment section.

They're either setting up exact time bots to post the "Liked myself" comment when I comment, or are Like hungry.

Theory: They may be sub beggars too.

If "I liked my own comment" was one entire personality, I would say it's a form of NPD, aka, Narcisstic Personality Disorder, which means you, and I mean YOU need severe help.

Just some quick advise to like stealers.
