Honestly, Imgflip as a whole would not care. But I would.
And I would mourn for the life lost, for the bright soul extinguished.
Do not do this, brother.
You have so much more of life to look forward to, think of what a waste it would be to throw it away! It can't all be fun and games but you can't do anything about it except roll with the punches and get back up again.
I see. Couldn't you just delete this account, come back on a different account, and don't make the same mistake twice, as opposed to ending your life?
You wouldn't be able to let anyone know that you are you but they wouldn't be the wiser.
