I remember him by seeing his YouTube channel a little while ago. Some of his videos where logical and coherent, others where a bit dodgy content wise. Most who leave the Incel community are either bored of it, busy or can't cope the information or just want to move on with life. Maybe deleting all his stuff is a way to move on or maybe he didn't feel safe and wanted a clean slate.

If something happened to him, his exit may have been more abrupt, though I am not sure if he has left a final message behind or not. It is fair to point out he did not have to delete his videos so there must be a greater driving force to not leave them up, maybe to not be tracked by his accounts.
