I recently noticed the same account commenting under a lot of videos about Amy Lee/Evanescence.

At first it stood out because the comments themselves were already kind of strange, long, hard to follow, and jumping between unrelated ideas. He often mixed things like religious references, personal claims, and random celebrity names in a way that didn’t really make sense.

Out of curiosity I checked the channel behind it, and that’s where it got even weirder.

The entire account is basically dedicated to her, with hundreds of videos that feel very rambling and repetitive. Some of them use similar language to the comments almost stream of consciousness, sometimes referring to her in very elevated or symbolic ways.

It didn’t come across as trolling to me, more like a very intense and possibly concerning level of fixation.
