You don't remember this because you're normal.
The only people who think ghosting is humorous and/or clever are people that are socially inept. And they try to justify others' disdain by saying we're pissed off we weren't in on the joke. No Loser - the only joke is you.
Seriously, anyone who would bother to go through the process of creating another username, coming up with another password and then hunting down a new avatar is fucked. Do you not feel silly waiting for the confirmation email from a forum saying you've been approved? Ooh... you got one over on us random people on the Internet. Even better is when the fukking loser and his ghost participate in the same thread. Awesome!!!
I'd suggest adding to your resume that you successfully ghost at a gambling forum although you most likely don't gamble consistently yourself. I'm hoping someone will be impressed. Let's ignore the dilemma of why one would be such a fukking loser to hang out at a gambling forum if they barely place any bets themselves in the first place. Unfortunately, thinking of how much time one must waste logging in and logging out only to fool people who literally don't give two shits if you live or die is quite depressing and I'm going to stop here.
Goog luck with it all.
