Mine were fairly recent and needed to be deleted several times to stay deleted. Seemed really random.

Keep your account for a while after deleting

Mine are staying delete now after initially a few popping back up. What’s more concerning is that I requested my data a few weeks after I deleted my content. I was fully expecting to get empty files but nope ALL of my content. Dating back 10 years is still there! It’s not on my Reddit profile but they clearly kept it somewhere and can recall it whenever they want to. They do not delete the data.

Ah it’s a tight race with the Twitter blue check mark
