just edit it out and cover it up; everyone will soon forget
I wish I had thought of that before
seriously don't take his advicedon't edit it out. if you do that, it'll get worse, because then people will also make fun of you for thinking editing it out would keep them from knowing you did it
Word of warning, do this too much and you'll end up like XhozerBut only just one or two posts is just fine.
you would be an ass if you kept pursuing him after he edits it out
imo just strikethrough it and add "Nevermind i'm dumb"
