I’m not 100% sure, which is why I didn’t name him initially until asked and clarified that is my guess. I noted the deleted x/twitter account earlier (I assume by “bad sign” you mean good sign it’s him?).
But I’d say I’m about 90% sure. You can see that x/twitter account posted at least as recently as January based on replies to it, and likely still existed on March 3rd when it was tagged by “NLWC fan.” But the best evidence IMO is that when I looked closer at the video I thought he looked kinda like the guy that had appeared in the BEG podcast, who I know was a PSU homer and FS fan (I believe he reported for them from Worlds in Serbia for example). But when I went to check the old videos all the ones with him in it have been deleted, despite what looks like most or all of the rest of their old videos still being posted.
